my last trophy was to prestige once in public match
i did that today, got my platinum
later i thought i'd do a complete backup of my game saves
then i restored just to see if it works, i'm back to 91% for black ops 2
but my gamecard clearly shows i'm already prestige 1
what can i do?
Yeah, it's those reasons why I sync my trophies almost immediately after earning, especially with Platinums. The data will only remember trophy information from the last sync, so if your PS3 died or you did a backup it would be inherently lost. Looks like you'll just have to Prestiage again.
