This isn't necessarily a bug, but it is probably an oversight. If you get Curse of the Giant on the Corpse floor, it is possible that rooms can generate with Coils (the electricity-shooting pillars) and other indestructible obstacles such that the amount of electricity beams becomes overwhelming and potentially unavoidable. Here is a room that generated with electricity beams blocking the door, leading to unavoidable damage.
This probably won't be easy to fix, but a possible solution might be making sure rooms with Coils don't spawn as the larger combined rooms.
