There was a thread some time ago about some of the undead that were supposed to regenerate after a party "killed" them, so that they had to be killed again. It was reported that some of these monsters weren't regenerating as they were supposed to. I've just been through the first dungeon inside the Chasm of the Dead again. In my game, the Skeleton Masters regenerated as they are supposed to and when they were re-killed, they sank gracefully into the floor, each leaving its little bag of goodies. The Skeleton Warriors, however, vanished into the floor leaving nothing, and did not come back. My game is patched up to v1.3.
