Hey, so i'm playing the quest "Arizona Killer" and i'm wearing the NcR Ranger armour to get past all the troops safely but as soon as i get there, they start killing me!
I've tryed the all the NcR armour in the game INCLUDING the one i'm specifically given by whosit but still no luck. I dont know what to do and i dont want to fail the quest. if this isnt a glitch, can you tell me what i'm doing wrong or why its caused? Thank you.

I'm viliied btw with NCR.
