 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!*      
      ----------------------      

Minecraft has stopped running because it encountered a problem; Unexpected error

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

Invalid due to mod issue.

Comment by Meta [ 30/Oct/12 ]

Oh yes, I forgot about that (have Optifine). With vanilla minecraft I get a message: "You logged in from another location." (also this one has no translations on crowdin.net too)

So that's no vanilla bug.
Please close.

Also, in your crash report: Is Modded: Very likely

This tracker is intended for vanilla minecraft clients and server. If you are using mods that invalidates the error report for us.

If you can duplicate the error with an unmodded server and client it would be more valuable to the devs.

I know but it should not crash then but instead display a message or something.

You cannot multiplay with a single account.
