The only dialog files in my override folder have to do with the Deadye on Manaan mod, and those are all spoken on Manaan, by Deadeye Duncan, so those can't be the cause.
The last line of dialog I get with Mission (in regards to her story) is the part where she first mentions Lena's name. ("I don't feel like talking about Griff and Lena! Just the thought of that space tramp makes my blood boil!") But after that, she never talks about it again. (At least on Taris)
Like I said, I used to be able to get her to spill the entire story before I went to Davik's estate with Canderous. Am I just overreacting to this?
