I've found five bugs from Teemu since release of v1.0. Four of them are fixed. Here is the one I have to fix:
Some of the areas are not connected and some items and monsters are created in them. I made sure that stairs are always generated in the origin point of room so it's pretty much the center of it and those points are always connected in other points with corridors so stairs never get created in detached pieces, but I should still fix them. It should be easy.
