Database acting weird for 1 person

Hey,

My database is not loading a character for 1 person properly. He keeps getting rolled back randomly, sometimes 2 days something a couple of hours. Every single day in the morning, but not when he logs out for dinner or something like that. The thing is, it's just this 1 person, and nobody else is having this issue. I had him make a new character, all was fine till server restarted. It just didn't load his player data back up, but there were no errors.

Help would be appreciated
