I have played through baldur's gate once, and I am in the process of playing it again with the tales of the sword coast. I have gotten to the fight in the dukes palace, but something is wrong. I'll finish the fight, but the dukes or sarevok don't do anything. I have the invitation, letter, and diary. Have I missed a trigger? Has anyone else found a bug in the game? I really don't want to start over again. Any help would be great.

see my 'Reloading triggers' thread for more info.
