At least this will help me a little,Yesterday same day as the DLC came out I lost connection to xbox live,I reconnected and my rank was reset to prestige 0 rank 1(was as prestige 4 rank 52).

I had golden mp7,evo,and CQB.Diamond knife,Crossbow,BS,And blastic knife).

So this might help me get them back
