game Crash

My game crashed, but it wasn't exactly a crash, it was more like the game froze. Normally with a crash, you get a loading buffer before the game does a white-out and then closes. Then when I restart the game, I'm backed up to the last saved location a few actions behind where I crashed. This time, the game just froze in place and it didn't stop running. I had to manually close the game myself, and when I reloaded the game I was right back in the location and position I was in when I froze. Just thought that was interesting because I've never had that happen to me before in this game.
