I found another bug too. When you go to the quarry under bloodhook and get the ore. If you talk to one of the cats at the entrance of that cave later on after that ore event is over he will say something about the ore you found and move down and to the right a few squares.
If you talk to him again he will move again. I havent tried seeing what happens when you keep doing this and he walks into the wall. I'm guessing the game will probably lock up.
I wonder if these bugs were in the original or introducted by the patch?
Will you grant me a wish when you find the Rune? Dream? That is... a secret.
