I bought the game on steam last october and got to about level 20 or so on multiplayer (codex on), as well as completed the campaign. I recently reinstalled the game after a reformat and now my account is completely reset, multi and single player (obviously losing the MP levels and all the grind that entailed is the most frustrating). I still retain achievements earned on steam despite this.
Is this normal or a bug? anyway to fix it? i certainly don't want to grind it all over, especially if it will just reset again next time i reformat.
