So I've noticed that falling in some rooms in Sky Islands (because i fall a LOT in sky islands) teleports u to some parallel pocket dimension room that doesnt exist on the map and crashes the game when you see it. It happens in rooms that shouldn't have anything beneath them anyway? Like the room before the gate to Farm Arrays I was knocked into the death pit by a vulture and saw a room with a shelter that can't be accessed. I fell on the bridge otw to chimney and fell into the same room but with a blue background and looked all glitchy. I'm bad at explaining but it's not a huge deal since I'm dead anyway when it happens
