      Description

      When clicking on "Multiplayer" and then quickly (before Minecraft has finished loading the server status, number of players etc.) trying to join a server, I get a NullPointerException (no crash):

      [20:24:00] [Client thread/INFO]: Connecting to mc.slicedlime.tv, 25586
      [20:24:00] [Server Connector #1/ERROR]: Couldn't connect to server
