For people wondering. No, I am not wearing an NCR enemy's armor. No, I don't have a gun out or holstered. No, I have not stolen anything from them. Yes, wearing NCR armor helps, but when im by quest characters they shoot me.
Atleast this isn't as bad as the save glitch I guess, but still this is stupid. I don't even understand how I how i have only neutral rep with the NCR in the first place. I didn't do anything to piss them off. I have actually helped them.
If you have any ideas to fix this issue please post them. (besides the ones I stated above)
