Holy shit, I've had a few games freeze up, like said by others, have to re-boot to start over. After this last update, I've had exactly one game not freeze up out of about 8 or 10. Now, I keep getting a Probation Period for quitting too many matches and can't play a public match for 5 minutes after I log back in.
I'm thinking it's time to take BO2, along with a few other older games, into gamestop and get something different. This is pretty ****ed up.
