Well i couldn't connect to any game servers since this morning. The server list is working fine though.

I could press connect to such servers, but the loading screen always stayed at " Setting up game..." and changed to another "Setting up game..." if the servers change the map.

But no gameplay was achieved

 

From the command i noticed some strange lines mentioning " client's XUID not matching slot 3( 11 ) in server "

Worse than that, the game may not load at all

No response from server. None.

Yet it still stays at " Setting up game.."

I also noticed that during the loading progress, "Synchro-ing game settings " appear and vanish quickly, then comes " Setting up game..." which is earlier than it normally does.

..

So have you guys experienced anything akin to this? And how can i repair it?
