Today I reinstalled everything to check if it was really virtue, but I am afraid it is so. After installing virtue the mod NPC's, Kelsey, Ghareth and Saerileth, ask everytime you load the game if they really should go. What I didn't tell them. There are also the strange happenings of Jaheira telling that she must 'oppose' me, while my virtue is 14. This all happens only when loading the game. Afterwards it works good, as far as I can tell, but it begins to annoy me that I constantly must tell people to stay and hearing NPC's get pissed (for Instance Minsc is also mad at me when loading within the same safe as Jaheira and thus this happens at virtue 14. I didn't use SK for anything in that save).
