It was a forest-like map iirc.
Exiting the game, and reloading a save gave some more bugs: After killing the boss in the farportal I was saved I used the portal. The fortress was reset (but I still had the energy and all the rest). I killed the weirding beast again to enter the fortress. All items where gone and the servant too. I could not insert the rod because I did it in my previous fortress. Anyway the fortress was totally bugged
.I will see later if I can reproduce this map generation bug and post a log.
