      Description

      When you are logged in on a server and start a second Minecraft session and join the same server, the first client crashes with (for me) following description:

            *Minecraft has crashed!*

      EDIT: THIS IS NOT A VANILLA ISSUE. I HAD OPTIFINE INSTALLED AND THAT SOMEHOW CAUSED THAT.
