Everyday now I see more and more people making things up about the game that aren't true and WE CAN ALL SEE IT by ourselves. Just stop being picky and play the game. Stop making things up.
Obviously the guy who's posted this thread is getting the issue when others aren't. I'm seeing many posts about issues but not everyones getting them. It sounds like you have a faulty disc, I'm running it from disc and it's absolutely fine, no issues whatsoever (bar the autosave yesterday)
