The dungeon generator of Kaduria is such an entity that it's hard to keep it in condition. When something is changed the generator can go bananas. This is what I got today:
It's trying to create a room in bad location, but it can recover from that and doesn't crash. I've made the map routines check out of bounds internal so it can't fail that way, but there can be areas that are disconnected. There is still some serious stuff to do with corridors and how they are connected. Corridors are always the problem.
