SPOILER ALERT
------------------------
I reached the point in the game where everyone starts getting sick and Lae'zel threatens to kill us all before she's talked down. After resting for the day, I can no longer talk to her. She wasn't in my party at the time. She has an exclamation mark, denoting she wants to talk to me. But I cannot get the conversation icon hovering over her. Nor can I click her. Tried rebooting the game [which has sometimes helped with other issues] to no avail. I guess she's really moody. She wants to talk to me, but refuses to. :P
