Did you by any chance recently install the AnyGameStarter? I am having the same problem you are describing since I installed it. I am not sure it is the cause, but since I didn't change anything else, it is suspicious.
ETA: Apparently other people have this problem too, I found this in the feedback thread:
I also noticed that Darren Dreamer has his usual dark skinned head, but a light skinned body. This is definitely not usual.
I am totally unawesome but maybe this has to do with a modified C:\programs:\EAgames folder, like when you prevent your game from goopyfying every new hood by renaming the thingy? Oh and uninstalling the AGS left my main game still borken.
