New gamerscore but no new achievements?

I recently reached a specific gamerscore and stopped earning achievements since then. I haven't earned an achievement in months according to the leaderboards but I have a new 75G unaccounted for. I was tracking my gamerscore in the days leading up to my
last achievement so I would have noticed if something didn't update correctly at the time. My theory is that an Xbox 360 achievement duplicated itself but that's just my best guess. Hoping to account for the new gamerscore and/or remove it.

add my gamertag looking for new peeps to play online and compare scores and achievements with had over 100,000 Gamerscore on x360 but decided new console new gamertag and new Gamerscore and friends

 

hello i am having problems with my gamer score rest

I am guessing that only you can see your modded gamerscore and everyone else can see your new gamerscore? So on your profile, you will see your modded gamerscore and your new gamerscore. But anyone else that views your profile will see the new gamerscore
only. I hope that makes sense. I assume its just for your reference.

 

Do you normally play offline? Maybe you’ve earned it a while ago and only now went online and it synced to your account? Either that or you just didn’t notice you earned it?

 

I always play online, and like I said I was tracking my achievements to make sure something like this didn't happen.
