Last night I had friends over playing some Halo 4 matchmaking for the first time as guests and everything was okay but when I tried to turn it on today it shows them still on the roster and at the bottom of the screen says "One or more players Xbox 360 Controller is disconnected". When I go to the roster menu and choose them it does not give me the option to sign them out, the only way to have them sign out is to sign out of my account then sign back in. This isn't a major problem or anything but I do find it kind of annoying and wanted to point it out.
