This happened to me yesterday as well on my Sorcerer. I have heard that the quest Secrets of the Darkest Stars is a wonderful albeit small story arc that really makes you feel like a member of the dark council. I have really been looking forward to it so I will not be touching my Sorcerer again until this is fixed. And that makes me quite sad because I have really been enjoying that character of late.

Ah, just what I was looking for. One question though, does this go for a mercenary contract as well?
