I'm having the same problem someone was having a few months ago. I have the expansion, and have registered it and the original game. I believe someone posted that you have to go to the Citadel to have Breza explain some side mission about Missing Amazons, but it never comes up. I'm in Chapter 2.
I have checked back,
-Before having to speak with Ashran
-After having spoken to Ashran,
-After having to speak with the other general
-I have checked back all through the story for the war that would happen if Loren and Company didn't go around investigating. Then no matter what, an event pops upto show you have to go to Hammerhead. After that I kept checking back, but Breza has a one track mind that Loren has to do this and that. I'm at a loss for words.
Why is conversation in Chapter 2 to access the Castle of N'mar content not popping up? I think I will have to hit Breza over the head and hypnotize her just to get her off this one trick pony that Loren needs (MInor Spoiler)
to go stop a war and convince everyone to work together.
(End Minor of Spoiler)
I played the game through once doing that and skipping all the Castle of N'mar content.
I'm gleefully thinking Breza should be on clean up duty for a month for Trouble the Hellhound just because she is technically blocking Loren and the others from having new adventures in the game.
