I just downloaded Old World Blues a few hours ago and started up New Vegas. My reputation for the NCR was "Liked" but after downloading it returned to "Neutral". It also happened to Freeside and a few other factions. I tried loading a previous save, but it didn't change. Does anyone else have this problem? If so how do I fix it.

If you're wearing clothing of a different faction, they will appear neutral no matter what. Taking off that clothing will return the reputation back to what it was.
