Same here. I play offline solo and mine crashes during loading process at "Ocean". First couple of days after last update it worked fine but today it crashes. I've tried playing solo online but that does not help.
Same here. I have an original Xbox and mine crashes every 12 to 13 minutes. And also about half of what I've already done in those last 12 minutes is gone. The whole not connected to the internet thing is probably not the game it's probably just Xbox because that does it with all my games when I play them offline.
