It was decided to go to a random community server without mods, a pure vanilla game. Server name: 1 mSx VANILLA CLASSIC. After logging back into this server, this error appeared: ERROR 0X00040033 (someone with your UID is still on the server message. It makes it impossible to log in to any other server. The problem persists all day on 31.12. I am very disappointed to buy a game for the new year that I can't even play.
