I've convinced Llorissa Faali to return to Emmurbalpitu, but when I get there, as she's standing in front of the ghosts + Aizuhr-Suur, the quest doesn't advance. Aizuhr-Suur just says "Let's hear what that foolish mortal has to say.", and Faali: "I'll see you in Emmurbalpitu. You have my word that I will be there.", both leading to a forced "Goodbye".

The quest stage I'm on is 55, "Llorissa Faali agreed to return to the Emmurbalpitu shrine to confront the ghosts of her brothers and sisters. I should return to the shrine and let Aizuhr-Suur know of this." Poking around the in CS, I can't find anything to indicate how the quest is supposed to advance, outside of manually setting the stage to 70. The ghosts are still left if I do that, however.
