The server is sending corrupt data
In 1.8.6, I often get this error message in game and ignoring it isn't an option. It usually happens at the time when my friend logs into the game.
The error is: The server is sending corrupt data: The player that was supposed to login, is already logged in. (id = 15432, 19)
Hope you can fix this before NCFC starts as I don't want this to happen to the livestreamer when he's playing my game.
