Sorry for all the complaining I've been doing recently, but I found another game-ending bug. So, I died in the ambush you get after finishing Dreadfell. Was the fact that I had already killed Ukruk important? Normally they'd just take the staff and run off leaving you alive, but I'm assuming they wanted to avenge their glorious leader so that's ok. Anyway, I came back, and found everything but the trees turned black and only the orcs right next to me visible. I died a second time, and this time the trees were gone too, as well as the way to the worldmap. Just me and the orcs in an empty black void of nothing.

(As a side note, if you've upgraded the RoR shouldn't it take you to Yiilkgur and _THEN_ dump you into the ambush when you go back to the surface? If you try to use the portal to escape, maybe it could stop you and give you a message like "You feel uneasy carrying about the staff. You should bring it to Last Hope before something bad happens.")
