Yes I am in the same boat. I have the guide and went to all the places listed in there, but I've done all the quests associated with each location. There are obviously other locations since the Lucky 38 isn't listed as a location for her to talk in the guide and I got her to talk there.
What I'd like to know is for Camp McCarran, Vault 3, Old Mormon Fort, Nipton and Nelson, does she comment once you discover the location or is it just randomly while you walk around? I've been going back and forth to these places constantly with no luck.
I really want to get this quest done with so I can work on getting the other Follower quests done.
For me she initiated conversation the first time I went into silver rush (halfway through the "boss discussion" and then had a couple of new dialog options under the BoS tree. Then, after I met mr house, she had new dialog, but didn't say anything until I talked to her. I've tried going to:
Novac
nipton
Talking to OSI man (hildern)
Talking to FOTA doctor woman (farkas)
Going to mccarran (inside terminal too)
I only need one more but nothing seems to work. Why are obsidian games ALWAYS so buggy? Or is is just me?
