Bwhaha, update on the bug list: I just had an Orcish War Drummer turn friendly. After the forced conversation between the guard and Dr. Elrath in the poor quarters, the Orc chasing me turned friendly and was able to converse. It gave the standard answer (Whoah! Put away that weapon friend! etc.), though I did get the "Buah - I cannot stand seeing you alive!" option afterwards
edit: Shit. It applied to ALL Orcs in the game! Including reputation loss if you attacked them, etc. Would be hi-fucking-larious if I wasn't trying to do a no reload game (and I wasn't going for the lowest rep possible). Still, I might just as well go that route now.
BTW, is there a list of known bugs somewhere? Just to avoid redundant posting.
