it does not affect gameplay but it is annoying

Does it happen in Single-Player?

not sure. i quit minecraft and saw the error in the game log. i was playing multi-player before i quit

If it happens on multiplayer only, it's a server error and should be reported to the server owners.

ok thanks

do you know what the error means?
