Game Center on my MacBook Air logs me out
Ever since the last system update, GameCenter on my MacBook Air logs me out for no apparent reason. When I start a new game I'm prompted to sign in again, and when I sign in through the game it shows me as "anonymous" with no achievements.
When I check in System Prefs, it shows as Anonymous. If I click on "View account" it takes me to the App Store where my avatar is blank and it says zero achievements -- but my achievements/activity is still listed.
If I log out of GameCenter in System Prefs and then turn it back on, after I sign in it does show my screen name and avatar correctly.
What's going on here? I don't have this problem on my iPhone.
