Same problem. Played local game ,the 3th february approximatly at 17pm/17;30pm, with my brother on the same ps3 in hope to get internet recovered. When it's happened, I returned to multiplayer game and seen all my stats back to the beginning. If you could restore us stats it would be very great. I know it's not always simple to get the game perfect and without defaults but it's very disappointing for gamers who buy a game and see it destroy their efforts. But of course I don't make reproachs or anything else, just highlight this fact. My PSN ID is : khefkorn and I was Prestige 2, around the 30ieth level.
