I just encountered an odd bug. The second floor of my current dungeon has absolutely no stores. I explored every inch of the darn thing, but none at all. There was a Monster Zoo... but no stores. I'm pretty sad about this, I was looking forward to donating some more things to the warehouse.
floors are randomly generated... having a no store level is a random occurrence. like having a level with 5 of them..
@Malignant Sorry, you're wrong about the 5 on a floor. There is a maximum of 3 on a floor. It's inside the Tweakdb.xml file. Having more than 3 shops is impossible without editing that file. tweak name="max shops" ival="3" This one in particular. Also, it's A. Very annoying, and B. Very rare. It may be random...but still.
