I was reading Qwinn's notes (from the beta version, with a further note that the problem appears to be in the release version too) about trouble with the Mae'Var quest terminating early in Chapter 6, but I couldn't figure out from that thread if there was a known workaround.
Like Qwinn, I accepted Renal's quest to investigate Mae'Var in Chapter 3, but I didn't get around to doing it until Chapter 6. When I got back to town in Chapter 6, I talked to Brega, but refused his request (my character is Neutral, and hey, the shadow theives may be a bad bunch, but they've helped me out a lot). Then I went back to Mae'Var, stole the necklace for him, talked to Edwin, and...bam! Edwin wants to accompany me to take out Mae'Var. I turn him down, and from there on out, "Edwin has nothing to say to you."
Is there any way to fix this, or should I just kiss Renal's quest goodbye (assuming I don't want to restore back to Chapter 3)?
