I have been playing online lately and twice when playing online I noticed that my profile information had disappeared. The gamerpic, bio, achievement score and rep all appeared as either empty or 0. I noticed this because while I had been playing I should have picked up some achievements and at one point they stopped, so upon pressing the Guide button that's when I noticed but my friend looked at my profile and it looked fine from his side.
I switched my console off and signed back in, everything was fine but it has happened again. Any suggestions?
