Friends appear then disappear, deleted friends reappear

i noticed some weird things going on. but nothing that prevented me from playing. I was playing with a friend and the car we were in was disappearing and reappearing. Also the map was disappearing. It eventually stopped but it some of the things you expect
when playing an MMO so it doesn't bother me to much.

Tenure has been wonky as heck as of late. Mine disappeared completely a month ago and still has not refreshed. Twitter support told me tenure counter is updated once a month (it is probably even longer than this considering my tenure still hasn't reappeared
a month later). My guess is that when the counter updates itself, it will appear at 10. Hopefully my tenure will return at that time. I've had 2 accounts and tenure disappeared on both. I've noticed a few friends whose tenures have also disappeared. I wish
the tenure system was better.

I have a friend request I can't decline as well. It just refers me to Xbox support when I try. I've tried on my console, Xbox.com & Smartglass. I even tried accepting the friend request & then removing the friend, which appears to work at first, but if I
sign out & sign back in the friend request reappears. Please help!

In a previous, now deleted comment, I mentioned my achievements/game history disappeared again, but it's back now. It seems to be an on and off thing, as some people mentioned that theirs disappear and then reappear again.

I'm just gonna play games, and be on the lookout if my achievements/game history disappears again.

I am having the same problem, one second they are all online then they are all appearing offline; even with hard resets. Some friends will reappear but a significant amount stay offline and I cant play with anyone.
