Heh I know I shouldn't be bringing this thread back up, especially since it is a bug report, but I couldn't help but add the thought that I always have when I see this bug:
A hero party???? Why wasn't *I* invited?!?!?! YOU BASTARDS!
I would have brought a cake, too...
What brought up this thought though, was I was wondering if this bug couldn't be turned into a "feature" instead... assuming it can be modified the way I think I can. What I'm thinking: it would make it alot easier to identify the locations of your heroes when they are not in your party, as well as the location of some wandering quest enemies. Instead of being forced to use the cheat menu in order to find some hero/enemy that has wandered off from where it is supposed to be, you will instead see a marker for "hero_party" or "quest_party" on the horizon. It would also be good for caravan escort quests, since right now you can't rest in an inn and hope to find your caravan again (assuming it is still alive, anyway...).
