So, I wanted to do the Helios one quest, and forgot to talk to the NCR Trooper lady at the front door before going in. Of course she flipped and went hostile and I just decided to load from an earlier save point. However, when I returned to Helios One the NCR troopers there are immediately hostile to me. My reputation with the NCR is Accepted and my Karma is very positive, so it's not like they were hostile to me before I even tried the quest.

Any ideas? I think I can just go do something else for a while and come back, but I wanted to know if maybe someone else has had this happen before and if maybe there was a console command people had used to reset people's hostility.
