So Ive been playing most of today, and i just noticed that my gamerscore is messed up. Online at xbox.com it shows up correctly, but locally on my machine its about 2k short. Yet, all my recent games have the correct #, its like my xbox forgot how to add.

sooooooo
wrong forum, meant to go in 360

I had this same problem a while back after recovering my account... After I signed in and out a few times the score was fixed...
