You did everything correct as far as I can see. I don't know why you got invalid membership and by now you probably know that the games were being synced to xbox live and take a little while to sync to your profile. That is why they were the offline, but not online. To all you other people...
Thank you very much. I do not want to lose my account and this makes me feel much better. Do you by any chance know how long it takes for them to catch you or is it completely random?
I have been looking for the answer of this and yes I used the search button and got many mixed results. Some say its console ban and some say it is just a reset, does anybody here actually know? I modded 20k gamerscore in 1 day like a dumb*** and just want to know what will happen.
