Same thing happening here. Beat the game, left it and it was gone. Started up campaign a second time and looked tonight and it was lost again. I won't be starting another game until we get an update for this. Multiplayer works perfectly (aside from typical lag and texture loading), all that progression stays saved.
Guys this is not just happening on ps3, I also have an xbox one, ps4 and the game BF4 has lost all game progress in campaign and multi player, so frustrating my copy of game is definitely being sold. Very disappointed. my advice avoid this game in the name of your sanity and blood pressure levels.
Weak,...I stopped playing for a few months hoping this would be fixed... jsut unlocked all on single player. Checked forums before going back online.
