IT'S OVER 9000!!!!My gamerscore messed up and now my score rating is absolutely insane, the achievement number keeps changing randomly and stuff and I don't know how to fix it (images below)
No they won't, they'll just reset your gamerscore to 0, that happened to me back when the 360 was still relevant..IT'S OVER 9000!!!!
I would not go online if you have modified your gamerscore since Microsoft can and will ban you.
