Barracks problem

every stat mod ive used for mw3 always changes the barracks score successfully, but never uploads to the leaderboard, is there any way of fixing this? having a stat hack is useless if you cant see its work

Just go online should save after a few games

Yeah what phusic said

Play a match to make it fetch your stats, it's the same on the consoles. If you change a class fx. then it doesn't save till you play a match.
