Bugs

This page shows a list of all bugs declared using the {{bug}} template that exist and can be reproduced in the latest version of the game.

Page	Description	Platform
??? (Floor)	Attempting to open the door leading to Hush's room while holding a Golden Key will cause Isaac to walk through the door without opening it, immediately beginning the Hush fight.	All
??? (Floor)	PS4 Mama Mega! cannot be used to open the door to ???.	XboxOne
2Spooky	When using D12 to reroll obstacles; any Movable TNT or Fire Places created within the radius will occasionally spawn as feared momentarily with only the purple tint to indicate the status effect. This effect lasts even on the remains of either object after it's destroyed before the fear effect ends. Corn poops created in the radius are unaffected however the Eternal Fly may also become temporarily feared.	All
4.5 Volt	With 9 Volt (and The Battery?), the gradual charge of 4.5 Volt is separate from 9 Volt's charge on one-charge items rather than being additive.	All
7 Seals	Each use of Glowing Hourglass that does not move Isaac to a different room from the one he is currently in (such as by teleporting to the previous room then using it again) will duplicate the locusts.	All
7 Seals	When playing Tainted Lazarus, the item can duplicate itself on hit for the current room.	All
A Lump of Coal	In Greed Mode, if Isaac picks upA Lump of Coal in a Silver Treasure Room and then fights Krampus,A Lump of Coal may still drop after the fight. Since this item's effect does not stack with itself, this will give Isaac a useless item.	All
Abaddon	If Keeper picks up Abaddon, it will remove all of his Coin Hearts but will not kill him until he picks up an item. This still applies if Abaddon is acquired via the Debug Console, but not if the item is picked up normally.	All
Abyss	According to locusts.xml, Ipecac locusts are supposed to explode. This never happens in game; Ipecac only gives a locust that deals slightly more damage and poisons enemies.	All
Abyss	Each use of Glowing Hourglass that does not move Isaac to a different room than the one he is currently in (such as the starting room of a new floor) will duplicate the locusts.	All
Achievements	Clear Rune must be unlocked and collected to attain !Platinum God! and The Real Platinum God despite being a Repentance item. This is due to its ID being unused in Rebirth, thus being in the ID range of Rebirth items.	All
Achievements	PS4 If installed, before unlocking it, the 'Challenges' trophy will require completing all the challenges available on the current DLC played instead of the original 20 Challenges.'"`UNIQ--ref-00000004-QINU`"'	All
Angel	Delirium can transform into Fallen Uriel and Fallen Gabriel but they do not have unique Delirium skins.	All
Ascent	Dropping a trinket in the exact same spot as an obstacle may despawn Cracked Key further down the road during Ascension.'"`UNIQ--ref-00000000-QINU`"'	All
Backasswards	While entering an exit to the previous floor, if the player kills the process (isaac-ng.exe) during the versus screen before a boss fight, re-entering the game will lead Isaac to the starting room of the previous floor instead of the boss room. This allows the player to finish the challenge pretty easily without any actual fights.	All
Backasswards	Sometimes the layout of the rooms makes traversing to the previous floor impossible. There might be a hole where the light is supposed to be and without flying, makes the run impossible to beat.	All
Backasswards	If Isaac is teleported into the I AM ERROR room on the final floor of the challenge, there will be no exit, making the run impossible to beat.	All
Beggar	Touching a Battery Bum while it is giving Isaac's active item a charge will grant another charge. Multiple additional charges can be gained this way.	All
Beggar	Will not payout correctly when trying to gain charges as Bethany.	All
Birthright	Playing as Keeper, having more than 3 HP, and entering the area in which Knife Piece 2 can be acquired will remove the fourth HP (can be increased back to 4 HP after)	All
Birthright	Playing as Magdalene, having more than 12 hearts, and entering the area in which Knife Piece 2 can be acquired will completely remove all hearts above 12.	All
Black Market	Creating and entering a trapdoor which also leads to a Black Market (for example by We Need To Go Deeper! or an Rune of Ehwaz rune) results in not being able to escape the Black Market other than going to the next floor.	All
Black Market	Using Telepills or Undefined to enter a black market in the mirrored world on Downpour II and Dross II will generate a black market with no items and no exits. Without any other means of teleporting, this will softlock a run.	All
Bob's Rotten Head	Although Bob's Rotten Head works normally with Butt Bombs and Bomber Boy has no effect, their combination drops the explosion damage by 50%.	All
Book of Virtues	As Tainted Isaac, dropping and picking up the uncombined Book of Virtues will refresh the item's charge, allowing for max wisps.	All
Book of Virtues	Each use of Glowing Hourglass that does not move Isaac to a different room from the one he is currently in (such as by teleporting to the previous room then using it again) will duplicate the wisps. Any extra wisps created from duplication on a filled ring will appear at the entrance of each room Isaac enters and shoot in the direction Isaac is currently shooting.	All
Book of Virtues	Using a Dice Room or being hit as Tainted Eden to reroll an uncombined Book of Virtues will result in it rerolling into a different passive item while still remaining in the active item slot. It will disappear when Isaac picks up a different active item.	All
Buttons	In trap rooms with retracting spikes, pressing the plate within five frames of the spikes deploying will cause them to appear to fail to retract, but this is only a visual bug, and they will not deal damage. This can be fixed by leaving the room and re-entering.	All
Buttons	If D12 creates a Reward Plate in the boss room on the floor where an alt door is allowed to appear (After A Secret Exit is unlocked), activating the button to create enemies and kill will create another one, up to 4 doors (depending on the size of the room). Exiting the boss room will leave only the original alt door. By entering a copy of the door, you can go to the alt floor and if you exit, the original door will also be open, even if you did not open it.	All
Cain	Cain's covered eye can be seen through the reflection on the floor on stages/rooms with water	All
Cantripped!	Receiving the Bag of Crafting as a card and using it will crash the game.	All
Car Battery	Mr. ME!: Grabbed items and pickups may become ghostly and impossible to pick up. Leaving the room and returning fixes this.	All
Cards and Runes	Rune of Hagalaz will open Secret Room doors in L-shaped rooms.	All
Cards and Runes	Using XVI - The Tower? in a Boss Room may block all paths to the trap door, resulting in a softlock if no bombs or flight are available.	All
Cards and Runes	Using XVI - The Tower? can also trap certain familiars over the rocks such as Lost Fly until Isaac leaves the room.	All
Cards and Runes	Any blue flies, blue spiders, friendly enemies, locusts, orbital bones, and wisps created by cards, runes, and soul stones can be multiplied when Glowing Hourglass teleports Isaac in a way that does not move him to a different room from the one he is currently in (such as by teleporting to the previous room then using it again).	All
Cards and Runes	As Tainted Lazarus, all effects of XIX - The Sun? except bone heart conversion and sprite change will disappear when flipping.	All
Cards and Runes	Entering the Knife Piece 2 area while under the effects of XIX - The Sun? will cause a visual bug wherein Isaac will revert to his default appearance but still be capable of flight and spectral tears.	All
Cards and Runes	If an activated collectible on a pedestal is touched and then rerolled with Soul of Isaac, the alternate item(s) will also count as "already picked up": they will not drop pickups, grant health or transformations they normally would.	All
Cards and Runes	If multiple Souls of the Forgotten / Jacob & Esau are used in the same room, only 1 forgotten/pair of Jacob & Esau will be removed after leaving the room. For every room that is left, one copy of them will disappear.	All
Cards and Runes	Using a Black Rune in a room with exactly one pickup and one item while being near the fly limit won't suck the item.	All
Chests	If a smaller chest is present in a room, re-entering the room will make the chest appear in a regular size.	All
Chests	Unless the player has enough keys, flight, or any form of teleportation, the Mega Chest can block the way of a narrow passage way and may even deny access to many other rooms such as the Boss Room, possibly softlocking your run.	All
Corpse	D12 still has a small chance to generate trapdoors in Corpse II. These trapdoors will lead Isaac to ???.	All
Crawl Space	If Isaac's hitbox is small enough (by using One Makes You Smaller pills), it's possible to travel through the walls and ceiling to access the Black Market. In the walls are much harder to clip through, but it can still be done with high speed and help of the stairs or flight.	All
Crawl Space	If Isaac uses a XXI - The World? card inside a Black Market and enters it, he will be taken to the crawl space that leads to the Black Market. If he then tries to leave the crawl space from here, he will be spawned back inside it making exiting to the main floor no longer possible. If this is done on the Chest, Dark Room, The Void, or Home floors it will result in a soft lock since Isaac cannot leave through the trap door that usually spawns in the Black Market.	All
Crown Of Light	If Isaac picks up a Bone Heart while the crown is glowing blue and leaves the current room, the crown will continue to glow blue even though the damage boost is inactive due to the Bone Heart container being empty. Taking any damage won't make the crown turn gray until Isaac fills all of his Red Heart containers and leaves the current room to reset the effect.	All
Curses	Curse of the Maze can still teleport Isaac to already explored rooms.	All
D12	Using D12 while Tainted Forgotten is sitting over a pit (not being thrown) will make his head and weapon disappear, rendering him unable to attack and preventing Tainted Soul from picking him up, unless the room is left or the run is exited and resumed. This can easily cause a soft-lock.	All
D12	If D12 creates a Reward Plate in the boss room on the floor where an alt door is allowed to appear (After A Secret Exit is unlocked), activating the button to create enemies and kill will create another one, up to 4 doors (depending on the size of the room). Exiting the boss room will leave only the original alt door. By entering a copy of the door, you can go to the alt floor and if you exit, the original door will also be open, even if you did not open it.	All
D12	When rerolling obstacles while Isaac has 2Spooky; any Movable TNT or Fire Places spawned in the fear radius has a chance of being spawned momentarily feared with only the purple tint to indicate the status effect. This effect lasts even on the remains of either object after it's destroyed before the fear effect ends. Corn poops created in the radius are unaffected however the Eternal Fly may also become temporarily feared. Venus has the same bug with the only difference being that it is charming obstacles and Eternal Flys and turning them pink	All
D4	Previously held items are not removed from the pause menu, which makes it difficult to determine which items Isaac currently has.	All
D4	When D4 is used with a co-op baby present, the baby's sprite will turn into a glitched sprite of Isaac.	All
D4	If Isaac rerolls Schoolbag, he will keep both active items, but if he picks up a new active item it will swap with the one currently selected and the other will disappear.	All
D4	When Schoolbag is rerolled away while another active item is held along D4, the other active item will be dropped on a pedestal. Activating D4 after the other active item is dropped will then reroll D4 itself.	All
D4	An item picked up is assigned the pool of the most recently generated item; usually this has correct results but a difference can be seen, for instance, by killing a boss, entering a Devil Deal that has items and collecting the boss reward after seeing the Devil items. The boss item will be rerolled to a Devil pool item with D4. Items with no item pool (starting items, fixed drops etc.) will always use the item pool of the most recently generated item from an item pool as a result; if no items from item pools were encountered yet, the treasure room pool is used.	All
D4	Items that are rerolled are assigned the pool of the item with the highest item ID. This means one reroll with the D4 will probably go as expected, but further rerolls will be proliferated by items from the pool that had the highest ID before the first reroll.	All
Dark Arts	Sometimes, if the player touches an enemy, Dark Arts can last shorter and end prematurely.[Check ingame]	All
Dark Arts	If you use Dark Arts after using Doctor's Remote, and before the missile hits the ground, you'll get stuck in the animation of holding the remote over your head until leaving the room or getting hit, not allowing you to fire tears.	All
Dead Sea Scrolls	If an effect triggers and adds to the character's appearance while being held (Monstro's Tooth or Kamikaze! for example), the additional visual effects will remain for the rest of the game or until they are replaced.	All
Debug Console	If a champion is spawned via the "spawn" command, it will have the same amount of health as the non-champion version of that monster, unless the spawned champion variant has decreased amount of health.	All
Debug Console	If the player has debug 10 enabled and starts the sequence to begin the Dogma fight, Dogma will instantly die without continuing the sequence, softlocking Isaac in the room without returning control to the player. This is fixed after exiting and continuing the game.	All
Debug Console	Using the "rewind" command removes all broken hearts on The Soul if there are any.	All
Debug Console	Debug Console may rarely break, and will not turn off.	All
Debug Console	Using debug 12 during the Knife Piece 2 sequence in Mines/Ashpit II will crash the game.	All
Deep Pockets	While holding Esau Jr., swapping to the character without Deep Pockets then collecting or spending coins will cap the number of coins at 99.	All
Delirium	If Delirium transforms into an enemy like Chub with multiple hitboxes, the game may crash if one of the secondary hitboxes is hit by Chaos Card.	All
Delirium	Delirium can transform into Fallen Uriel, Fallen Gabriel, Bumbino, and The Pile, but they do not have unique Delirium skins.	All
Delirium	If Delirium transforms into Mega Satan, the sprites will bug out. It can attack normally, but the sprite may not be visible/half-visible/only showing the hands.	All
Delirium	On Isaac's last will, Delirium will be shown in its current form rather than its main one. Sometimes it will show his main form, even if Isaac is killed by a different form.	All
Delirium	Delirium can sometimes deal unavoidable damage. For example, when transformed into Mom, the Boss will constantly target Isaac until it stomps down. If Delirium changes during this targeting phase, it can teleport into Isaac, instantly damaging him.	All
Delirium	Sometimes, when Delirium transforms into a segmented boss, its health will appear to be lower than it is. This is usually purely visual and returns to normal whenever it transforms again.	All
Delirium	If Delirium transforms into Blue Champion Larry Jr. it will, due to how Blue Champion Larry Jr.'s HP works, effectively lose a large portion of HP as its total HP will get divided into however many segments it transforms into. It will not receive the lost HP back after transforming again.	All
Delirium	If Delirious is used to spawn Hush, Delirium will be able to transform into Hush.	All
Delirium	If Delirium transforms into Gemini, Suture will stay in its enraged form separated from Contusion when Delirium transforms again.	All
Delirium	If Delirium transforms into Blighted Ovum, Suture will keep its usual sprite instead of using its special sprite for Delirium.	All
Delirium	If Delirium transforms into the Mask Of Infamy, it will only transform into the heart.	All
Delirium	If Delirium transforms into The Frail, it will always transform into the first phase, regardless of how much hp it has left (unless it's the Black Champion version).	All
Delirium	If Delirium transforms into Lokii, it will only transform into one Lokii half.	All
Delirium	If Delirium transforms into War's second phase, the body will be invisible (except for when it does its sobbing animation) This also applies to Blighted Ovum's Contusion.	All
Delirium	As of patch V1.7.8, if Delirium transforms into a champion boss, it will retain its normal appearance and color, but its attacks (and size in the case of some forms) will be those of the champion.	All
Dirty Mind	Each use of Glowing Hourglass that does not move Isaac to a different room from the one he is currently in (such as by teleporting to the previous room then using it again) will duplicate Dip Familiars.	All
Dogma	If the player were to add Dogma into a room outside of Home via Debug Console and defeat both phases, the cutscene with Isaac and The Beast will play as normal but the game will crash shortly after, due to a sequence break.	All
Dogma	If the player dies at the same time as killing Dogma's second phase and has extra lives that make him respawn outside of the room, the fight will reset to the start when entering the room again. The static transitioning effect that starts at the end of the fight will remain on the screen after reviving, making it very difficult to see anything during the rematch.	All
Donation Machine	If Isaac donates to the machine, leaves the room, and the game is then restarted using the PS button, the machine will retain its donation and Isaac will have the same amount of coins as he started the current floor with.	Vita
Dr. Fetus	The black ring generated from the synergy of Dr. Fetus and Tech X behaves as a File:Collectible Maw of the Void icon.pngMaw of the Void ring and may cause Black Hearts to drop.	All
Dr. Fetus	Even though having spectral tears will make bombs not collide with obstacles, if Isaac shoots a bomb while on top of an obstacle, the bomb will collide with it, making it possible to take damage.	All
Dull Razor	Habit will charge Dull Razor if Isaac has The Battery.	All
Eye of the Occult	After the first Brimstone shot, the Twisted Pair familiars will be unable to fire until Isaac moves the crosshair and even then they will often only fire once or not at all. Chocolate Milk fixes this.	All
Familiar	Exiting the game and re-entering will cause all Blue Spiders to disappear.	3DS
Flush!	Flush! works against Lil Haunts but it can softlock the game.	All
Found Soul	Resuming a Jacob and Esau run with Found Soul equipped in Esau's trinket slot will require a controller to continue. If a controller is available and plugged in, Found Soul can be controlled like a Co-op baby and won't mimic either brother's movements. This effect won't happen if Jacob holds the trinket. If no controller is available, the run is softlocked and cannot be continued.	All
Found Soul	When used together with Azazel's Stump, the soul familiar sometimes keeps Azazel's properties (flight and short brimstone) for a few rooms after Isaac has transformed back to normal. Lil Clot also has this bug.	All
Found Soul	If Sulfur has been used in a room before picking up Found Soul, it will retain Brimstone until dropped/killed, even through rooms.	All
Found Soul	Entering one of the portals created by Card Reading, Lil Portal, and Ventricle Razor causes the familiar to become invisible until Isaac drops and picks up the trinket again or sometimes from entering a new floor.	All
Found Soul	The game will crash if Found Soul collides with a Confessional, and the game will crash upon attempting to reload the run, effectively terminating it.	All
Friendly Ball	Certain monsters will not spawn friendly enemies when defeated: Moter Swinger Dinga Black Globin's Body	All
Gaper	If a Dark-Red champion Frowning Gaper does not become a Pacer or Gusher and regenerates, the head won't appear until it sees Isaac. The same goes for a Gaper, however the head won't appear at all.	All
Gaper	If an Explosivo tear is stuck to a Nulls when it becomes invisible, the tear will fall to the ground.	All
Gaper	The Explosivo tear will instakill a Nulls when it becomes invisible.	All
Gaper	If a Champion Gaper is killed and it turns into a Pacer or Gusher, it will no longer be a champion.	All
Genesis	Using Genesis immediately after taking Dad's Note will teleport Isaac to the Genesis room, then to the start of the ascent with no items except those that cannot be removed (Dad's Note, Key Pieces, etc.).	All
Genesis	Genesis removes wisps created by Lemegeton but not the item effects associated with them. These remain permanently active until Lemegeton is used again.	All
Glowing Hourglass	For some reason, having Error trinket with you will make your familiars "respawn" each time you use Glowing Hourglass, which leads for some interesting interactions. For example, Buddy in a Box and 7 Seals will change their forms each time leap, and the Star of Bethlehem will change its position to the room where you ended up after the time leap, allowing you to move it where you want it to be.	All
Glowing Hourglass	Going back in time will add one more copy of each familiar that were created by Monster Manual for the duration of the room you ended up in, regardless if you have it with you or not. Exiting this room and using Glowing Hourglass again will add another copy for each time leap you do, it will still last untill you will exit that room and will be reset afterwards.	All
Glowing Hourglass	Going back to the starting room will undo some map-revealing effects, such as The Compass.	All
Glowing Hourglass	If a new game is started and Eden begins with this item, using it in the first room will remove Eden's starting items.	All
Glowing Hourglass	Using the reworked Glowing Hourglass in the starting room in Greed mode or Greedier mode will result in a game crash.	All
Golden Trinket	Golden trinkets rerolled by D20 will cause the resulting pickup to have the golden effect applied to it. If this is a trinket, the trinket will turn into a standard trinket, otherwise the gold effect will do nothing and will disappear upon leaving and re-entering the room. Additionally, items spawned by chests with the gold effect applied will be golden as well, however other pickups dropped by chests will not be.	All
Great Gideon	Spawning Great Gideon with the debug console will spawn him with a normal boss healthbar instead of a "waves" mechanic. When Great Gideon attempts to spawn a wave of enemies, the game crashes.	All
Great Gideon	Dealing enough damage quickly enough (e.g. with Soy Milk) to the monsters Great Gideon creates can cause him to spawn the next wave before all enemies in the current one are dead.	All
Greed Mode	If the Super Secret Room is generated behind the locked (golden) Treasure Room, it is possible to get stuck by teleporting into before unlocking the Treasure Room. The Treasure Room doors all become unlocked when one of them is, unlike the normal game mode where a Treasure Room may have only one locked door, which results in the bombable wall between the Super Secret Room and the Treasure Room also being "locked". It cannot be bombed or opened with a key from inside the Super Secret Room, and unless another means of teleporting is available, the run is softlocked.	All
Greed Mode	Using Genesis forces you down a new "Ultra Greed" floor instead of the safe place, even if the final boss is already killed.	All
Greed Mode	Dream Catcher shows the wrong items in Greed mode.	All
Guppy's Hairball	Killing the Hush Flies that Hush spawns does not increase the hairball's level.	All
Guppy's Paw	If Keeper uses Guppy's Paw to remove all his Coin Hearts, he will not die until he picks up an item.	All
Gurglings	If the player stays close to walls, the Gurglings will not charge.	All
Gurglings	If both Gurglings charge at once, only one of the Gurgling's grunting noise file will play.	All
Gurglings	When fought in the Boss Challenge Room, they will appear in their enemy form rather than their boss form, making them much weaker and lacking a health bar.	All
Gurglings	When the Gurglings are slowed and attempt to charge Isaac, they can't move and constantly spawn Attack Flies. Similarly, the "mini-boss" Gurglings attempting the same attack will constantly shoot 6 blood tears.	All
Haemolacria	When using The Forgotten's melee attack with both Jacob's Ladder and Haemolacria, the sparks caused by splattered tears will hurt the player. (Video clip)	All
Haemolacria	Using Mom's Knife and Marked with Haemolacria will cause it to only fire towards the center of room, using the fire buttons will barely move the Marked icon; while Mom's Knife will be unusable and locked to the right.	All
Health	A Gold Heart surrounding a Soul, Black, or empty Bone Heart will be used if a Red Heart is depleted via the alternate order before the rightmost heart is lost.	All
Health	Losing many hearts at once, such as via Dead Cat or a Hematemesis pill, while having a Gold Heart will trigger the Gold Heart loss effect many times at once, showering the player in coins.	All
Holy Water	If Isaac has the Extension Cord and Holy Water breaks, the sprite is temporarily stored just off the top-left of the screen, where the yellow beams will still connect to it.	All
Home	If the player uses Delirious during The Beast fight, and it summons Rag Man during The Ultra Harbingers phase, the battle will softlock or crash due to the dead Rag Man's Raglings counting as enemies	All
Homunculus	If an Explosivo tear is stuck to a Begotten, when it becomes invisible, the tear will fall to the ground.	All
Homunculus	In the "RoomEditor" modding tool, Homunculi cannot be placed.	All
Hush	If Delirious is used in phase 2 of the Hush fight and Delirium is killed, The Calm (music usually played after defeating a boss) will replace Morituros.	All
Hush	Having the No Return seed enabled when going to Hush will result in no doors being available, softlocking the run.	All
Hush	Stop Watch / Broken Watch / Using the I'm Drowsy... pill makes the lasers from Hush's eyes late in the fight impossible to avoid, because their speed is calculated based on Isaac's base speed, not accounting for Isaac's slowing effect.	All
Hush	If Hush takes too much knockback too quickly (e.g. from Knockout Drops), the Hush Flies it spawns may teleport around the room erratically, occasionally resulting in unavoidable damage.	All
Isaac (Boss)	The Angelic Babies always spawn in the bottom center of the room at the same position.	All
Isaac's Heart	When picked up by Tainted Lazarus after picking up Birthright, the character which has Isaac's Heart can be damaged even in ghost form.	All
Isaac's Tears	With Brimstone and Chocolate Milk, the attack can be charged past the fully charged point, firing massive, extremely damaging tears when Isaac's Tears is used.	All
Isaac's Tears	When Isaac's Tears is in the first active item slot of Schoolbag, the secondary item does not charge upon clearing rooms.	All
It Lives	Sometimes, if the boss intro is skipped, the game will not teleport Isaac into the center of the bottom of the room, resulting in immediate contact damage with one of the Eyes or It Lives, depending on the direction of the room's entrance.	All
Jar of Flies	The synergy of The Ludovico Technique with Brimstone or Technology will not spawn flies.	All
Keeper	Guppy's Collar respawns Keeper with half a soul heart	All
Keeper	Entering the Knife Piece 2 chase sequence with Birthright will negate the effect of the Birthright. Picking up an HP up will fix this.	All
Kidney Stone	If Kidney Stone activates while a charged tear effect such as Tech X or Chocolate Milk is currently charging, the charge will get stuck, unable to fire for a somewhat-short period of time, before eventually having the Kidney stone be released as normal. Tears will then occasionally charge, even if a fire button isn't held down anymore.	All
Knight	The hitbox of Dark Red Champion Knights (and their variants) do not change when they crumble into goo, and they must be shot from the back to damage them.	All
Lazarus	Lazarus will receive a copy of Anemic when resurrecting. The item does nothing when stacked.	All
Lil Portal	If a portal is reencountered during the ascent, such as in a previously completed boss room, the game may crash if the destination the portal originally connected to no longer exists in the now altered floor layout.	All
Lil Portal	A portal can be created next to a door which can block off an entire section of the map and cause a soft lock.	All
Lil Portal	Entering one of the portals causes the Found Soul familiar to become invisible until Isaac drops and picks up the trinket again or enters a new floor.	All
Lil Portal	Activating Glowing Hourglass twice after Lil Portal consumed the last forth pickup will make him drop a portal while the pickups will stay untouched in the room. If you wont move after a second Glowing Hourglass activation Lil Portal will drop a portal right at the entrance, which will block it and may cause a softlock.	All
Little Horn (Item)	The item's effect cannot be triggered on Mobile Hosts while they walk.	All
Machines	In the Booster Pack 5 update, the Fortune Telling Machine's fortunes are broken and display as a garbled mess.	Switch
Marked	Mom's Knife + Haemolacria: Causes the crosshair to follow the camera instead of player input. In normal rooms this makes the crosshair get stuck in the middle. In larger rooms, the marker will only move when the camera moves, allowing for minimal control when aiming due to how the camera moves based on the direction Isaac is currently aiming.	All
Mausoleum	If the LABY RNTH (permanent curse of the labyrinth) special seed is being used, the door to the mausoleum in Mines/Ashpit generates very infrequently.	All
Maw Of The Void	When combined with Chocolate Milk, Cursed Eye, Monstro's Lung or Tech X, releasing a Maw Of The Void attack may prevent a charged shot from firing at the same time as expected. The charged shot is delayed by about ~0.5 seconds. Holding a full charge for a longer time makes the delay more likely to happen.	All
Meat Cleaver	If used on Reap Creep, during his 3rd Phase, he cannot properly collide with the walls in order to perform his rock attack and will infinitely run against the wall.	All
Meat Cleaver	If used against Mom's foot, both will count as their own instance, and the second foot will only be able to be killed once the first one is dead. If the first foot is killed instantly, the second foot may never drop, requiring a reset.	All
Meat Cleaver	If used during Min-Min's phase change, both bosses will be unable to be damaged.	All
Meat Cleaver	If used on The Stain, the boss will be back to normal size when poking out of the ground. This is most likely due to the boss becoming smaller when going underground and therefore overriding the size it was given by the Meat Cleaver.	All
Mega Mush	Activating Mega Mush before entering the Knife Piece 2 area will keep the effect active inside the chase area but Isaac will have his normal sized, followed with a huge shadow and will continuously stomp the ground, breaking everything in his way, even pushing away Mother's Shadow.	All
Mega Mush	If Isaac walks over a Teleport Pitfall while Mega Mush is active a visual bug will occur where the pitfall is destroyed and can no longer harm Isaac however its sprites still remain in the room. When Isaac reenters the room or exits and continues the run, the teleport pitfall works normally again.	All
Mega Mush	Using Mega Mush in combination with Suplex! makes you grab enemies and move them around until you leave the room. Doing this on any of the Ultra Harbingers or The Beast will make the enemy disappear and render you unable to move at all.	All
Mega Mush	Activating Mega Mush through Void will cause Isaac to visually revert to normal after leaving the room while still under the item's effects. If Isaac does not have flight, a stomping sound will play and the screen will shake constantly even if he is not moving.	All
Mega Mush	When Mega Mush times out and Isaac returns to normal size, he may occasionally appear to have no head. Isaac is unable to fire tears in this form and cannot interact with enemies or objects or pick up items. He also cannot interact with trap doors or Crawl Space entrances, causing softlocks. Exiting and continuing the run fixes this issue.	All
Mega Satan	Doing too much damage between phases will cause the game to play the normal "boss defeated" music throughout the rest of the fight.	All
Mega Satan	If a Pickup spawns under Mega Satan's hand, the hand will start to move and rotate for the rest of the fight until it's pushed away. This is a purely cosmetic bug.	All
Mega Satan	Using Delirious in Mega Satan's fight (after stepping on the pentagram), if Mama Gurdy is spawned, Mama Gurdy will be spawned behind Mega Satan, but it will be able to attack.	All
Mega Satan	If Isaac has Mom's Box and Tick, Mega Satan will start the fight at 70% health, instantly starting the fight at the first wave of bosses. Afterwards, Mega Satan will be invisible the entire fight, and if Isaac moves to the upper half of the arena before Mega Satan dies, the game will softlock.	All
Member Card	Using XVI - The Tower? in the underground Shop can spawn rocks under the ladder, resulting in a softlock if Isaac can't fly or doesn't have any bombs.	All
Member Card	Using IV - The Emperor? in the underground Shop on Mausoleum II, and getting Rotgut as the boss, will result in an infinite loop of entering and exiting the boss room and the shop, respectively.	All
Member Card	On Downpour II (or one of it's alternate versions) : Don't go into the underground shop. Go in the mirror world, enter the underground shop's alternate mirror version. It should have nothing for sale. Make the game refill shop. For example by using a restock machine. Go to the regular underground shop in the normal non-mirror world. Now the underground shop contains two overlapped sets of things on sale : One from when the mirror version was restocked, and one from when you entered the "real" underground shop for the first time.	All
Member Card	While playing as Tainted Lazarus : Enter the trapdoor created by Member Card. Teleport to I AM ERROR, for example using Undefined. Use Flip to swap to the other form of Tained Lazarus. Spawn and enter a Crawl Space, Isaac will spawn in the center of the room. Upon exiting the crawl space Isaac will be placed in the Member Card shop, but will be softlocked as the exit ladder will now place him back in the Member Card shop.	All
Metronome	It is possible for this item to give an indefinite Breath of Life effect that persists throughout rooms, eventually killing the player.	PC
Metronome	If Urn of Souls is activated through Metronome, it won't shoot fire and Isaac could get stuck with the urn in his hands unable to shoot tears. You can fix this by exiting and continuing the run, restarting the room without the urn and without Metronome charges.	PC
Mirrored World	Spawning items with a Restock Machine in a Member Card mirrored shop will result in them overlapping with the items in the non mirrored Member Card shop.	All
Mom's Heart	Sometimes, if the boss intro is skipped, the game will not teleport Isaac into the center of the bottom of the room, resulting in immediate contact damage with one of the Eyes or Mom's Heart, depending on the direction of the room's entrance.	All
Monsters	Some Champion enemies that turn into another enemy when killed (Gurgle turning into Splasher for instance) will become invisible.	PS4
Montezuma's Revenge	When playing as Tainted Forgotten, the charge attack will always come out of the left of the body regardless of the direction it or the Soul is facing.	PC
Montezuma's Revenge	When combined with Chocolate Milk, Cursed Eye, Monstro's Lung or Tech X, releasing a Montezuma's Revenge attack may prevent a charged shot from firing at the same time as expected. The charged shot is delayed by about ~0.5 seconds. Holding a full charge for a longer time makes the delay more likely to happen.	All
Mother	If Mother is killed using the "Quick Kill" debug flag, the final boss chest will not spawn, soft-locking the game.	All
Mother	Broken Modem may crash the game during the Mother fight at a random time, usually related to the wrist burst attack. The attack does not always cause a crash.	All
Mother	When entering the corpse for the first time: the item unlock screen for defeating Mother as the current character may appear, but the item nor the secret screen won't be unlocked.	All
Mother's Shadow	If the game is saved and exited while in the sub-area, when it is continued, Isaac's visual appearance will match his items; however, items will still have no effect. It will revert to his plain appearance after either changing rooms or picking up a Throwable Bomb.	All
Mother's Shadow	Familiars with levels/stages will revert to their base form upon exiting the sub-area as the game does not internally store their levels. This includes, but is not limited to: Bumbo, Guppy's Hairball, etc.	All
Mr. Maw	If a Swinger's neck touches a red poop, the neck sometimes disappears while the Swinger keeps swinging.	All
Mucormycosis	During the Ultra Greed fight if a spore attaches to an Ultra Greed coin enemy, it may make the coins movement erratic and cause it to bounce around the room uncontrollably.	All
Mystery Egg	When using Extension Cord with Mystery Egg, after the egg turns into a friendly enemy, the electricity shoots out into a random corner of the room.	All
Mystery Egg	When the egg turns into a friendly Heart ( Mask + Heart) will sometimes act as the heart companion for a mask already in the room resulting in an unbeatable room.	All
Onan's Streak	If Judas misses a tear and picks up the trophy while getting hit, he will be frozen in position. Going to the main menu and continuing the run solves this.	All
Pause	If you activate and resume "Pause" while an enemy emits projectiles, the bullets won't proceed with regular but instead extremely decreased speed. However, they will still pass intended range, which bypasses the effect of shot speed being reduced as it normally would with any items that slow projectiles down.	All
Pause	When used with Dad's Ring/Monstrance/Saturnus it creates a second ring/aura/circle of light that stays in place where Isaac used "Pause" which lasts for the active item's duration. The second ring/aura/circle is a visual glitch and does not interact with enemies. Moreover, both rings/auras/circles are flashing for the duration. When used while Telekinesis is active Pause creates a second ring that stays in place where Isaac used "Pause" which lasts for Telekinesis's remaining duration. Moreover both rings are flashing and the second ring can not block enemy tears for the duration. Any tears that were still caught in Telekinesis’s radius before using Pause become incredibly slowed and indefinitely follow Isaac until he shoots. The items Salvation, Spear Of Destiny, and Trinity Shield all have a similar bug however these items are completely unable to interact with enemies (or block enemy tears for the shield) while Pause is activated.	All
Pause	When used with Star of Bethlehem the light aura will be stuck in the last position before Pause was used even if the familiar continues without it. This is only a visual glitch, Isaac still has to be near the star to receive its benefits. If Pause’s effect ends the light instantly disappears and respawns back around the star again. The light will still fade when the star leaves the room.	All
Pause	When used with Dark Arts, the player can unintentionally Soft-lock themselves if the Pause item is used during the effects of Dark Arts, this can be fixed by quitting then entering the game again. This is because Dark Arts does not finish its animation due to the pause item locking it in place. In addition to this, the player cannot escape this soft-lock via the fire button due to the player not being able to fire during the effects of Dark Arts. Moreover if this bug happens while Tainted Judas has Birthright, the dark aura around Tainted Judas will experience a visual bug from Pause that is similar to Monstrance.	All
Poops	If a golden poop is destroyed by an item pedestal spawning, collecting the item then leaving and re-entering the room will cause the golden poop to reappear, dropping its coins twice.	All
Red Redemption	Being revived by Missing Poster / Broken Ankh or transformed into Esau Jr. removes the Red Key and does not allow you to open new rooms, soft-locking you.	All
Red Redemption	Exiting and continuing a run while more than one Dark Esau is present removes all but one. This can be repeated for every new Dark Esau keeping the total count at one while enabling the player to continue using the Red Key.	All
Revelation	When combined with Chocolate Milk, Cursed Eye, Monstro's Lung or Tech X, releasing a Revelation attack may prevent a charged shot from firing at the same time as expected. The charged shot is delayed by about ~0.5 seconds. Holding a full charge for a longer time makes the delay more likely to happen.	All
Sacrificial Altar	If used to sacrifice Succubus while Isaac is in its dark aura, the damage multiplier will remain active for the remainder of the floor.	All
Satan	If exactly 600 HP of damage is dealt to Satan, it will completely skip the third phase and spawn the chest, due to how the boss is coded to go to the third phase only if over 600 damage is dealt. The easiest way to do this is to use only familiars to do damage, or to use 6 bombs (without modifications) against Satan's second phase.	All
Saturnus	Using Glowing Hourglass will trigger the effect of Saturnus again when returning to the room that was teleported out of, doubling the tears in that room.	All
Saturnus	When Pause is used with Saturnus, it creates a second circle that stays in place where Isaac used "Pause" which lasts for the active item's duration. The second circle is a visual glitch and can't hold any orbiting tears. Moreover, both circles are flashing for the duration.	All
Saturnus	In the first room of a floor, orbiting tears will appear elsewhere in the room and then be packed in two groups orbiting Isaac, instead of appearing on Isaac and then orbiting with an equivalent distance between each. They will turn back to normal when going to another room. This also happens in Mom's room after using her bed.	All
Secret Room	After defeating an Angel spawned in a Super Secret Room, the music will not return to the floor's regular music.	All
Secret Room	After fighting Greed/Super Greed spawn inside a Secret Room, if there is an adjacent Challenge Room or Boss Challenge Room, the metal bars from the Greed/Super Greed fight will not disappear after the fight has ended, making it impossible to enter the Challenge/Boss Challenge room this way.	All
Secret Room	Teleporting to the Super Secret Room in Greed or Greedier Mode, when the room is generated behind a still-locked Treasure Room, can trap Isaac inside.	All
Secret Room	Certain secret rooms result in a crash (observed on seed THWM 9284, Dank Depths II)	All
Seeds	Entering the Blue Womb while using the "N0RE TVRN" seed is not recommended as the door leading to the Boss Room will not spawn, thereby trapping the player and ending the run.	All
Seeds	Returning to the menu from a run that uses a seed that alters audio speed will cause the main menu audio to remain altered. This resets upon entering a new run, or exiting the game.	All
Seeds	The PAC1F1SM seed does not allow you to finish a The Beast run. Dogma never transforms in his second phase. If you manage to go to the Beast fight (with the debug console), the Chest spawns before Ultra Famine is killed.	All
Shoop da Whoop!	Using the item at the same time that you touch a large Golden Chest (dropped by final bosses such as The Lamb and ???) will freeze Isaac, and the ending won't appear. Leaving and re-entering the run will fix the bug.	All
Spear Of Destiny	If the Spear Of Destiny is removed from the player's items (for example, when using the D4), the spear will stay on in the level in the position where it was before the item was lost until Isaac moves to another room. This is purely a visual bug.	All
Spear Of Destiny	When Pause is used with Spear Of Destiny it creates a second spear that stays in place where Isaac used "Pause" which lasts for the active item's duration. Moreover, both spears are flashing and can not interact with enemies for the duration.	All
Spear Of Destiny	Swapping characters using Esau Jr. or as Tainted Lazarus will leave a stationary copy of the spear until Isaac leaves the room. The stationary spear is only visual, lacking collision.	All
Spear Of Destiny	The spear sometimes separates from the player.	All
SPEED!	During the mom fight she does significantly fewer attacks making the fight especially difficult as the only way to hurt mom is to trigger the hand attack.	All
SPEED!	If you successfully complete the challenge after the soft limit, you can still fail by taking ANY timer damage while the trophy-gathering animation is taking place. Taking timer damage during the trophy-gathering animation will cause your inputs to freeze and the trophy to disappear without actually finishing the challenge. You must either die or exit & re-enter the game if this happens.	All
Spirit Sword	When reaching 30.00 Tear Rate or higher, Spirit Sword will continuously use the spin attack, only stopped by holding down a fire key. This is likely due to the fact that starting at 30.00 Tear Rate, the internal number is "0", and begins to go negative beyond that.	All
Spirit Sword	In waterlogged rooms, the reflection of the sword swings in the opposite direction of the actual sword, when it should swing in the same direction.	All
Suicide King (Challenge)	If the game crashes during the challenge and is reloaded, Lazarus will lose Ipecac and have his normal tears.	XboxOne
Tainted Eden	If Tainted Eden is firing Technology 2 when damage triggers a re-roll, sometimes the laser persists firing in the last-fired direction until leaving the room, even picking up new synergies as other items reroll.	All
Tainted Eden	If the active item is re-rolled into Alabaster Box it will be fully charged instead of discharged as usual.	All
Tainted Eden	If Tainted Eden is resurrected during a Co-op game after dying, their graphics will break, cycling between Isaac's head and body.	All
Tainted Eden	If Tainted Eden first looks at an item on a floor (such as treasure room items, shop items, golden chest item drops, etc), but does not take them until after walking into a new room with an item in it (such as a Devil/Angel room), those items will be re-rolled into items of the pool most recently walked into.	All
Tainted Eden	If Tainted Eden rerolls into modded items that must be unlocked to be acquired, and they are not unlocked, the item will be rerolled into nothing, and you will lose an item. This can also cause crashes.	All
Tainted Eve	When Tainted Eve enters a boss room which moves her to a different starting position, such as Mom or Gurdy, the clots will not move with her, potentially leaving both Eve and the clots extremely vulnerable for a moment.	All
Tainted Forgotten	Evis can grab Tainted Soul. If Tainted Forgotten is not nearby, it can result in Tainted Soul having no way to kill the enemy.	All
Tainted Forgotten	Gaping Maws and Broken Gaping Maws can pull Tainted Forgotten inside them, rendering Tainted Soul unable to pick him up.	All
Tainted Forgotten	In rooms with reflective floors, while the Tainted Forgotten is being held, the reflection shows it below the Tainted Soul instead of over it, though its bone club is in the correct position.	All
Tainted Keeper	Mr. Maw and Mr. Red Maw will not always drop coins upon death.	All
Tainted Lazarus	Exiting the run during the second or third wave of a Challenge Room will forcibly flip Tainted Lazarus when the run is continued.	All
Tainted Lazarus	If Tainted Lazarus uses Decap Attack and switches forms without recovering his head, upon switching back again that form's tears will appear from a point seperate from his body, until Decap Attack is used again.	All
Tainted Lazarus	When fighting Rotgut, whichever form was used for the first phase will temporarily become invisible after killing the third phase and Rotgut's death animation plays. This is purely visual.	All
Tainted Lazarus	If the player teleports out during an active Greed Mode wave, going back to the room will prevent the player from switching forms during waves until he reaches the wave that he was previously on. This is not the case if the waves were completed before the timer has ended.	All
Tainted Lazarus	Doing a RERUN when Birthright was obtained will spawn an additional alternate form of the character.	All
Tainted Lazarus	When Tainted Lazarus has Birthright, his inactive form, despite being immune to external damage, can still be damaged by poisonous gas from destroying mushrooms and by The Pile's spike attack. The inactive form can also be damaged if it has Isaac's Heart and Birthright.	All
Tainted Lazarus	When Tainted Lazarus uses flip while having Birthright through Lemegeton, the now active form won't be able to pickup the item until the room is re-entered	All
Tainted Lazarus	One form of Tainted Lazarus may appear to be stuck in ghost form after leaving the Mirrored World. This affects appearance only.	All
Tainted Lazarus	If Tainted Lazarus teleports (Mausoleum/Gehenna's teleporters or Stitches) at the same time as the room clears, he will NOT flip between forms.	All
Tainted Lazarus	The harbingers from item 7 Seals, can duplicate themself on hit for the current room when you're playing Tainted Lazarus.	All
Tainted Lazarus	If at least one character has Spear Of Destiny or Trinity Shield, swapping to the other character causes these items to leave a stationary copy of themselves until Isaac leaves the room. The stationary spear is only a visual bug with no collision while the stationary shield still blocks tears.	All
Tainted Magdalene	Rotten hearts will not deplete when playing as Tainted Magdalene. Additionally, if you have more than 4 Rotten Hearts, Bone, Soul, and Black Hearts will not drain. If your pulsating heart containers are all filled with rotten hearts and and have more than one half a red heart in your permanent heart containers, your permanent red hearts will be drained.	All
Tech X	The black ring generated from the synergy of Dr. Fetus and Tech X behaves as a Maw Of The Void ring and may cause black hearts to drop.	All
Tech X	Having Tech X with Soy Milk / Almond Milk and Kidney Stone causes Isaac unable to fire laser rings when Kidney Stone is active.	All
The Beast	If the player has Knockout Drops, a sufficiently high amount of luck, and an item that fires multiple tears at once (such as Monstro's Lung), they will be capable of knocking the Ultra Harbingers far off the screen during The Beast's fight. This also occurs if the player has Strange Attractor and enough sources of tears being fired. Ocular Rift and Lodestone can provide similar effects.	All
The Binding of Isaac: Afterbirth †	If an angel statue is broken inside the devil room the door will incorrectly be shown to be open, but can't be escaped from	All
The Binding of Isaac: Afterbirth †	When Scolex is slowed, some of his body parts may detach or won't even show up - they will only be visible while entering the ground (especially the tail).	All
The Boomerang	The Boomerang can collide with The Ladder when deployed, causing it to immediately return to Isaac when thrown. It doesn't always happen.	All
The Forgotten	Making a deal with the devil that kills The Forgotten and switching into The Soul before ending the animation will make only The Soul playable, and vice versa. If The Forgotten is no longer playable, The Soul will be locked to the range of the chain. This will effectively softlock the run unless you also have Birthright.	All
The Forgotten	If The Forgotten obtains Brimstone right after the bone club is thrown (via items like D4 or Dice Room or debug console), a barrage of knives is fired instead of a brimstone ball.	All
The Forgotten	Very rarely, The Forgotten's head will permanently vanish when picking up his first passive item. This bug remains unfixed even after restarting the game.	PS4
The Lamb	If The Lamb is shooting projectiles and you damage it over half of its health, it will continue to fire until dead or it has finished its attack.	All
The Lamb	Killing the body in around 5 seconds will make the body stand inside of the chest, making you unable to reach it (and end the game). You can fix this by going in and out of the room.	All
The Lamb	With the special seed BASEMENT and coming with the last sacrifice room reward, opening The Lamb's chest makes the game crash.	All
The Void	A Stoney can spawn alone in a room, causing it to instantly die.	All
Tractor Beam	Tractor Beam has unusual effects when combined with Continuum and Pop!.'"`UNIQ--ref-0000009E-QINU`"' While shooting, tears will appear for brief moments at the back of Isaac's head, and if he hits an enemy with one of these, that enemy will be teleported to a corner of the screen for poorly understood reasons. Isaac himself can also get teleported to a corner, resulting in a potential softlock without flight or How to Jump.	All
Trinity Shield	When Pause is used with Trinity Shield it creates a second shield that stays in place where Isaac used "Pause" which lasts for the active item's duration. Moreover both shields are flashing and can not block enemy tears for the duration.	All
Trinity Shield	Swapping characters using Esau Jr. or as Tainted Lazarus will leave a stationary copy of the shield until Isaac leaves the room. The stationary shield still blocks tears.	All
Ultra Greed	If Ultra Greed is defeated at the bottom of the room, the ending chest will spawn incorrectly, causing it to be unreachable.	All
Ultra Greed	If Ultra Greed is hit by a Chaos Card after being turned into gold, his death animation will replay and cause a lot of gut splatter.	All
Ultra Greed	If the player dies and respawns outside of the room while Ultra Greed is rolling his eyes like a slot machine, the slot machine sound will play continuously until the game is paused.	All
Ultra Greed	Ultra Greed can 1-shot the player if they have Metal Plate, Cone Head, or other possible items.'"`UNIQ--ref-00000050-QINU`"'	All
Ultra Greed	If the player manages to constantly push back Ultra Greed while he charges so that he won't touch one of the walls, he will become stuck in his charge animation and won't do anything else until defeated. This can be easily done with Ocular Rift or Knockout Drops and a high amount of luck or tears.	All
Venus	When using D12 to reroll obstacles; any Movable TNT or Fire Places created within the charm aura will occasionally spawn as charmed for 2 seconds with only the pink tint to indicate the status effect. Corn poops created in the charm aura are unaffected however the Eternal Fly may also become temporarily charmed.	All
Vibrant Bulb	Replacing Isaac's active item with another active item that doesn't have a charge bar won't immediately activate the trinket's effects. The effect will depend on whether or not the previous item had a full charge or not. Furthermore, if the effect is active due to the previous item having a full charge, picking up a different active item that currently has no charge won't disable the effect, and vice-versa.	All
Vis	If a Vis (or any of its variants) is stunned, scared, or shrunken, it will still attack the player while running away from Isaac.	All
Void	Sacrificial Altar is fully absorbed, unlike other single-use active items, allowing Isaac to sacrifice familiars and obtain Devil Room items with each activation of Void.	All
Void	If Isaac has overcharge from The Battery, using absorbed items that Isaac can "put away" (e.g. Shoop da Whoop!, Bob's Rotten Head, Eraser, and Notched Axe) will use all the overcharge, even when Isaac puts away the items. In the case of Notched Axe on its own, using Void will use all charges at once.	All
Void	Pedestal items do not vanish instantly upon Void usage, allowing for an item to be obtained despite using Void on it. While the animation when using the Void prevents picking up pedestal items, this can be circumvented by cancelling the animation (e.g. using bombs or timed damage mechanisms like Shard of Glass) or by having another player.	All
Wavy Cap	There is currently a bug on Playstation 4 and Playstation 5 where using the item causes the game to crash.	All
Wavy Cap	If the player continues a save after maximizing the use of the Wavy Cap, they will respawn with the fire rate increase and changed appearance, but none of the screen effects. The screen effects will return at the same intensity once a room is cleared.	All
