Forum:Man! New Vegas is so stupid! :(

Spoilers?:

Well I've been playing a lot. I've got to New Vegas and did a bunch of things. Anyways im at the point where I look for info on why the squaters are getting attacked. On my way to a squatting area, i came across the Silver Rush. I let my weapons go, and entered. I heard a shot and accidentally left the building. Later I'd learn this is a bug.

I'm here to ask to see if it's possible to somehow fix this. My save games are no good because now those guys hate me (it autosaved!!!) etc etc. Do I have an option how to resolve this?
