June 6 patch
 

I've let my server stay up and run and when i notice someone trying to log on it does the same thing by kicking them off with unknown opcode, lol im sure it makes them mad, but wasn't sure if it would affect others if they didn't download the patch to log onto my server. But it seems it does so im not going to bring my server up again until i get it working. Sorry Gary!(Gary was the name one of the characters that got kicked hehe)
