Update 11/18/13:
Okay so placing my save data on the PS+ online storage is currently keeping my campaign data from resetting. Not sure if this will make any difference. I've booted the game up a few times and it still shows my saved campaign where I last restarted it from, Shanghai on Hard. On Battlelog it shows that I achieved all the story-related assignments, but in the in-game Awards section only a few show up.
Please note that I have confirmed that the multiplayer weapons locked in SP will stay unlocked even if your Campaign resets. I have access to all the locked weapons, like the M249 and the Machete.
