Anyone else having problems with this game frequently freezing? I've had my PS3 for almost 4 years and have played probably 20+ disc-based games (not to mention 30+ PSN games) and I've never had a freezing issue more that 2 or 3 times. But with this game, it's frozen at least half a dozen times (where I've had to restart with the power switch on the back of the PS3), and my data even got corrupted to the point of having to restart a new game once already.

Anyone else?
