I'm having a strange problem (maybe it as intended).

I'm currently liked by powder gang (while wearing regular non rep armor), however if I run into any powder gang outside the prison they still attack me unless I put on an powder gang uniform. This doesn't occur with any of the other rep (currently anyway).

The other strange bug I'm getting is, I've set the kill cam mode to "off" and the annoying kill "shot" scene still occurs which mess up my timing and gets me killed.

Is anyone else having these problems?

I think those are always set as hostile.

There are "Escaped Convicts" a splinter group of the powder gangers that are always hostile.

I'm not talking about escaped convicts, I'm talking about powder gang (labeled as such) at powder gang locations such as their camps (like the one near that airplane) before you get to the prison. The escaped convicts will attack you even if you're wearing powder gang outfits (at least they did with me). It's just annoying that I have to carry powder gang uniform with me even through I'm already liked by them. Kinda defeats the purpose of being friendly to the powder gang.

Several people had this happen with different factions. It is most probably bug. All powdergangers should be at last neutral to you after you visited prison unless you have very bad reputation with them.

From one of our senior producers:

The powder gang is not a real faction, nobody in the vault cares about the other group in the prison, nobody in the prison cares about the revolt leader in the vault or the outside camps. Unless you look like a powder ganger why shouldn't they attack you. Would be a stupid ambush "Excuse me Sir, are you friendly with the powder gangers? If not, I will kick your ass!"

The problem with these [censored]s is that if you shoot them, your rep with the REAL Powder Gangers takes a hit.

I call [censored] on that one.

If that was true Talchia, then everyone would shoot everyone on sight. NCR would assume that you're just an powder gang/legion/BoS/anyone else they shoot on sight, as someone out of "uniform". If you kill a "powder gang" you take a powder gang rep hit even if they attack you without cause. And it's a real faction, because you can do quest for them which I've done

I'm going to assume it just a hard to track bug to be fixed.

Actually, it's mentioned in the game. If you're on friendly terms with the Powder Gangers and talk with the leader Eddie, he tells you that you are okay with them, for now. But to stay away from their camps because they'll still attack you on sight.

Yeah the two by Jean Sky Diving, always hostile no matter the rep and will only be friendly if you put on a PG uniform.
And if you kill them you lose overall PG rep so they're not escaped convicts.
I call bug.
Obsidian fixpl0x?Kthx.

They are just a bunch of criminals, no social structure and communication is done by notes. The khans are also primitive, you can kill their leader and nobody notice it. The NCR has a giant network of radio stations, BoS Scout patrols, Mr.Hous a army of robots and the Legion lots of runners. By the way, I am a brute melee character and get no decrease in rep because they hit me first.

Yet they don't turn hostile at me even though I slaughtered their forces in Primm, Forlon Hope, Mojave Outpost and a ranger station.

What do the Power Gangers do for you besides being a Target?

I have never really concerned myself with whether they like me or not.

Well, they have a doctor, they have a merchant, some quests, oh and if you get on their good side they'll supply you with explosives every 24 hours.
