Legion hostile on first encounter @ Nipton

[Whargoul]

Hey guy's I was trying to do a pure evil run through siding with Legion but I ran into a problem with Vulpes and his noob squad being hostile to me at Nipton. This is my first encounter with them and the game tells me that my rep is Neutral with Legion faction. I am running the game pure vanilla with no mods. Does anyone have an idea as to why they are hostile? I only have one save and I'd rather not butcher Vulpes at this point and time. I pretty much destroyed goodsprings, primm, and the NCRCF. I noticed the NCR during the prison takeover was not hostile to me even though I had on a powder ganger outfit. I'm just wearing leather armor atm now.

Maybe it's a hiccup: go away, wait 72 in-game hours and go back.
I was also guessing the faction removal glitch, but that results in everyone being neutral to you, even hostile critters.
Did you accidentally kill anyone on the crosses near the town hall? That starts hostility. So is sometimes accidentally exiting the booby-trapped house with the scorpions right behind you (they sometimes know how to use the door, don't ask me how).

You might've killed someone important, could just be a weird glitch. My advice is just walk away from Nipton and talk to him when in Vegas, he'll pardon all your crimes and you'll be neutral again.

[B.O.S.]

sometimes happens...

maybe you were shooting one of the scorpions in the area and a lost bullet hit a dog or a legion dude... it's just an example... it's almost impossible to know the real causes in these cases...

I did kill thomas for his lucky necklace outside town. I also had my weapon drawn when I entered Nipton. That's the only thing I can think of. I think my game just glitched out to be honest. This never happened in any of my other playthroughs. I ended up starting again anyway with J E Sawyer's mod since the vanilla game was far too easy.
