remade dungeon and anything connected to encounter room 2 with spawns seems to disappear, rooms go to inventory, Items in attached room get lost in limbo. have to destroy entire dungeon to get them back. Also after remaking spawns did not spawn in any rooms that were still there
Edit: I moved the room around and have managed to get it to stay and not delet stuff, but it took a few trys. The issue is something with encounter room 2, as it waas always in the center of everything that disappeared.
