I forcibly retrieved the Platinum Chip from Benny and kacked his bodyguards up in the Tops presidential suite. Okay, so far so good. I end up fleeing from the Tops because every Chairman downstairs has gone hostile. Arcade and ED-E wipe out every Chairman down in the casino, Swank included - I never unholstered my holdout gun. I came back a week or so later so I could get the Talent Pool quest and the minute I step into the theater, bullets start flying. I fly out of the Tops again and decide that Talent Pool is off the table. So much for improving my Strip rep that way.

My question is, I know it's realistic (for a given value of realism) for everyone to react that way, but I thought that hostility was supposed to go away after a few days. Is this a glitch of some sort or is it just the way things are in New Vegas as opposed to FO3?

Do you have any faction armor on that they would react hostile to?
