Battelog Stats Different than In Game BF4 Stats

I've been having it happen as well, ever since 11/20. It seems like my stats are 5 or 6 games behind me.

For Example... In the attack jets, I unlocked the Hydra Rockets 2 games ago, but on my stats page it says I have 2,000 more points to go before I can unlock them.

got same problem

Like after a round you leveled up. Then on the next round you are actually not promoted.

How dare you worry about your stats showing different.

The game is deleting people's save data through Battlelog.  I think you can handle a delay in your stats. 

EA fix the corrupted save data already... Playstation 4, Battlefield 4.  Unplayable.

I have both of these problems. I've had my campaign data erased to the point that I have given up on SP. From what I have gotten through, it is only mediocre at best. I'm having tons of fun with MP but there are still a few hiccups. At least in my situation, the stat differential is not a delay it is actually different. I hadn't picked up the game in a few days and the stats were still the same (same unmatched value).
