I haven't searched too extensively, so this may very well have been brought up. But I just discovered a lovely bug in which upon loading, half my party is not where they were upon saving, but materialize on the other end of the dungeon, in an unexplored room, surrounded by enemies. Of course they die instantly, leaving my party sundered and unable to progress or retreat. So my options seem to be: battle with half a party and no wizard to my dead companions- Not likely. Or revert to my last hard save. I can't imagine an alternate solution to this, but if anyone knows one....
