Battlefield 4 Backend (Stats for Servers)

Hi all just was on a Server that our Clan has which crashed. Which in itself was not a problem. How ever even though no config changes have been made it would now seem to be a issue where my Rank and all my unlocked weapons are gone.

So i wonder if anyone else has this issue. If so does dice know about this i know there is maintance tomorrow but this is taking the mick a bit.
