Bugs[edit | edit source]

Bug Bug! Removing Schoolbag by means of D100 D100D100 Icon.png6 roomsUpon use, rerolls all passive items on Isaac like the D4, every pedestal item in the room like The D6, and every pickup like the D20., D4 D4D4 Icon.png6 roomsRerolls all of Isaac's items., or through being granted the effect from Added in Afterbirth †Metronome MetronomeMetronome Icon.png2 roomsGrants a random item effect for the current room. and using it again, does not cause the second active item to be removed or dropped into a pedestal; Isaac will still be able to hold his second active item until he picks up another active item, which will then remove the second slot and delete the active item contained.
Bug Bug! Re-rolling by Dice Room removes the primary active item but the second one remains unchanged, allowing another active item to be picked up. Picking up another active item after this will result in the previous bug; the second slot is removed and the active item contained is deleted.
Bug Bug! As of V1.06.J168, the item inside the Schoolbag has a minor graphical glitch when picking up a third active item. For a single frame as the pickup animation ends, the item's "charged glow" status and number of bars will match the item that Isaac is picking up.
