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.
