At first: I am sorry for my very old school english :-)
My system: Kubuntu 11.04 64.bit and Firefox 5.0
When I start a Practice Match with 8 Players then are in the game only 3, 4 or 5 Players.
I see for a short time this message:
was kicked by invalid name
I cannot added Bots in the game too. They disapear with the same message.
I hope you can help me.
