This is the first time I have ever dumped Jahs after starting the game with her so I am not sure what to blame. I received the quest from Aran to go to the docks at dark. I walk toward the docks (not quite dark yet) and pass the Harper's building where Jahs is standing. She initiaties a dialogue with me resulting in player shock so I didn't a get a good look at what it was. As far as I know, no NPC that you have dumped out of your party should initiate dialogue thereafter. I certainly didn't click on her and it wasn't a joining type dialogue anyway.
On another note I had played before with version 1 of the quest pack and had the problem mentioned below that the harper quests with Jahs never occurred. It may not have taken me 40 days to finish from that particular point but I have always gotten the harper quests before. Jahs is always other than this time in my parties. After this game, I'll see what happens with version 2 of the quest pack, Jahs, and the harper quests.
