I just finished an early part of the game that I've played through three times before, but in thus playthrough I am having problems. I have helped the NCR attack the ncrfc camp, but when I get to nipton tge legion attacks me while I'm wearing metal armor.
I am at a decent early point of the game, but I'm unsure if this is a game bug, or if I've provoked the legion somehow. Like ive said, I played through nearly three times already and haven't had this exact faction problem.
I have worn NCR armor briefly in mojave outpost but quickly changed back after leaving.
