On the quest for Cass where you find out who is responsible for taking out her caravan and others, you can pursue a non-violent solution by finding evidence in both the Crimson Caravan and VanGraff's safes. You can steal the key for the safe from the Crimson Caravan boss and open her safe, however taking the VanGraff key will not help you get into the safe (and it is a Very Hard lock, compared to the caravan's Average lock safe).
EDIT: I forgot these too:
-Reloading animation is screwed up for the grenade launcher (not rifle)
-I wiped out Nelson before even discovering Camp Forlorn Hope and finished the main quest there (the major congratulated me on wiping them out all by myself). But, I'm wondering, aren't NCR forces supposed to move into nelson? The only things in Nelson now are legion mongrels.
-I think the unmarked quest for the McCarrin quartermaster is bugged, I made the deal w/ the disguised ranger and the quartermaster but nothing else has come of it.
