I was really enjoying the game, but seem to have hit a bug that is killing me with frustration. I was on Troll Trouble, and went to talk to Sile, and I get no option to do so at all. So I went to the tavern, and started the Kayran quest. Still, totally unable to interact with her. I even took out a sword and tried to kill her just to see if I could, and, nope. She reacts, but nothing happens.

Any advice? I'd hate to ditch the game for this, but I'm definitely not starting over from the beginning if that's what has to be done.
