[Milk]

I was in the bar at just outside mausoleum and there's a Dustman in there called Waiting to die or something like that, and he asked me to kill him so I did, then the whole bar turn aggressive to me. I also have quests with people in the bar but now they just try to kill me, and my save before I killed the guy is ages and ages in the past.

My question is, can I get the bar folk to stop hating on me, or is that it now, do I just have to forget about the quests I have with them?
