Game system freeze

Ok so like i said, my PS3 froze when i was grinding arte usage in a battle in TOV. It was a Game System Freeze. And i was signed in online onto the PSN network on my PS3 PSN account, so I guess what bothers me and worries me is that the records and records that get recorded and uploaded online to the online leaderboards are or will be or can get corrupted. Not sure if they can? :/  Can someone help me and tell me what you think or know plz
