At an earlier point I'd exhausted all the dialogue after entering the Chapel of Light - only to realize as they marched out there were still people I hadn't assisted/rescued. (I found four groups afterward.) Now that I have everyone free to help, I can't get to that point again as the Ayleid king's dialogue options are gone and everyone remains seated at the table.
Logging out and back in, quitting and starting, or abandoning the quest in any combination don't help. This is going on two weeks now.
