So I wast about to turn in a quest for the caravan company when out of nowhere they started attacking me even though my rep with them is neutral.

I wasnt aware that being neutral means that they shoot you on sight.

So heres what I remember doing prior to becoming neutral (from liked): (this is barely a spoiler, only thing is what quests ive done)

I've looked at my saves and from one save to another it just magically changed my rep to neutral, I hadnt done any quests or killing in between these 2 saves. Im thinking this is a glitch but input from others would be nice.

Also im not wearing any faction armor.

So is this some sort of glitch ? If so how can I get out of it and if not how can I gain my rep back so I can turn this quest in ?

Are you wearing anything that changes your faction? If you wear anything legion, they'll shoot you. If the ncr doesn't like you and you are disguised and a guard sees you, they'll shoot you too. I think they shoot at great khans and powder gangers too

Im wearing Combar Armor Reinforced MK2 and ive tried removing all my armor before entering and it didnt help.

I think the AI is a bit buggy at times. The bots that guard the gate to the strip have turned on me just for being in a gunfight near them...no I didn't accidentally shoot them, I've had Great Khan's turn on me for shooting Legion assassins in front of them. NCR have flipped on me occasionally, also. Oddly Legion have been the most trustworthy in this regard. Hell, most of them stay friendly even when you're persona non grata...Ave'

Powder Ganger's have been absolutely frippin unpredictable for me lately, though AWOP may be responsible for that one. The PG Bullies are almost always hostile no matter my standing, though a few stay green just long enough to lure me in close for the kill. The normal PGer's usually stay neutral, although every once in a while they turn red after I get close. Been like this since I re-installed, changing up my mods slightly.

Probably a glitch, leaving them alone for a couple of game days should make them act normally again.

It might also be because they are like the same characters from somewhere else. Did u piss off caravan guards somewhere that wasn't at the crimson caravan? Unless they're all attacking you, that means the ncr hates u. R u an ncr terrorist by any chance?
