I recently had my Xbox account stolen. FIFA. *sigh*

Anyway, I only log onto Live every few weeks to sync my achievements with the servers, and I managed to almost 100% Rage (minus multiplayer achievements) inbetween logons. Meaning, when my stolen account is recovered, I'm going to lose all of those achievements

But I keep my save games. So the question is: Will achievements unlock retroactively when I load my save game? I have a save right before the end which I can use to recover my completion achievements, but there are quite a few progress achievements that I will lose. It would really burn having to play through the whole game again to get them. Awesome game - I'm just not a 'replay' kind of guy. I don't watch movies twice, either. I just don't have the time

Please tell me it's all going to be okay...
