what on earth has happeneded, went to sign in, my detail wernt there like normal, signed in manually to find some of my dog tags gone, all my custom classes wiped, certain module upgrades still there, others gone like retreiver which i had maxxed up,

lost permantly?

Have you tried rebooting the game? otherwise if rebooting doesn't work it's probally gone for good. That's what happen to my preset sniper class. I unlocked at level 10 and then it relocked itself when I reached level 17. Now there's no way to that preset class because I'm at level 23. If your playing on unranked servers unlocked dogs during those matches don't get saved. As for modules it's most likely a bug in the game, it tends to happen when your level is low.

i installed crysis 2 about 5 days ago and and now about level 12.
around level 9 i unlocked the m60 (my 2nd weapon unlock) and got about 20 kills with it in my custom class.
then later decided to switch back to scar and so i switched to scar for my custom class 1 played a few matches looked at my guns and it said i had not unlocked the m60 light machine gun (Though i did unlock it earlier). That is my problem is there any way i can get it back. Seems to me it is possibly some kind of bug or glitch. Is there anyway i can get that m60 back cuz when it relocked itself i didnt get my weapon unlock back. It also happened again when i went to unlock the grendel. It relocked itself yet i still had the gun equiped on custom class 2. That does not make sense and i lost all my weapon unlocks, i had 2 and lost bpoth for unlocking one weapon. It seems to be a growing problem among the crysis community considering i have talked to and read on forums of other people with the same problem.

Too delete dogtags -.-

Crytek fail!
