questions about shar-teel, firkraag and conster, sub-quest (spoilers) might be question for vlad Options

[ucsb]

I currently playing nej with the following set up (soa-tob-patch-weidu-ts-nej) and have the following question. I have shar-teel in my party and when I go to get firkraag for the first time he has a dialog with her and I can leave or go find some traitor. However it seems as if when she is in the party conster does not dimension door out so we can save the girl upstairs regardless of my answers. Is this a normal problem where I have to go find the traitor first and then we fight or maybe just a bug? Conster leaves to go upstairs as normal if Shar-teel is not near Firkraag, but if you don't have her talk to him the first time he has nothing to say to her after that. Any ideas on this would be great, and as a spoiler where can I find this traitor.

Thanks much in advance.
