hi folks, i dont know if anyone else has this problem, it has been bugging me since i bought the game.
whenever is get out of crysis 2 i lose about 5 rounds of previous data, so if i rank up i lose it, i lose everything i do ad it eally is annoying as i cant be bothered to do things over and over again.

Did you use the Search-Function?

Unlocks not saving - Potential workaround - Please advise...

im having a saving problem where after i unlock things in the customize equipment menu, it resets to where i have to buy it all again, and i dont think im being refunded the unlock points i spent in the first place. Its getting extremely annoying when ive created a custom equipment setup and its not available when im playing a game, meaning im constantly stuck with the only the default weapons and suit modules one is given from square one. is there anything that can be done to fix this?

Yeah.
Before you go to customize Equip join a ranked, empty Server. When u in there customize all u want, leave the server, it says "Updating Profile Data".
Restart Your game, your custom Equip should be there now without doing it all again... Works fine for me and i always do this to save my stats before i leave the Game.
Good Luck
