Freezing after opening maps

[robstacraw]

I opened a Westpoint map and the game froze up a little bit with the blue ring of thinking. I then alt-tabed out, then back in and it was working again, so I decided to open a another map (this time it was riverside I think) and the game froze completely. I exited out of everything and restarted the game. When I loaded the game again, it started me out where I was with the same equipment that I had previously, but instead of being about 1400ish, it was 0530 and my car wasn't outside and I backtracked on foot to the only places that I had it for the last two in-game days without spotting it.
