Raslin posted a fix to this in another thread, it didn't work for some, myself included, but I found one that does.
BE WARNED: Doing this bypasses key story elements and sequences in the game, in fact you skip a good part of the pelican bay missions by doing this.
Khoo Edit: I'm going to edit this message for now. There's a crack going around that causes the Zadora bug, and I'd rather not have stuff like this floating around. If for some reason you're running into the Zadora bug on your copy, please contact [email protected]. Thanks!
