The problem is this: AIs flood the client with packets which the client
takes forever to process. After that the server declares endgame and
floods the client a bit more with the entire map. The client is so bogged
down with the massive amount of packets that need processing that when the
server sends the ping packet the client doesn't reply in time and gets
disconnected. You can set the timeout value (in the tcptimeout variable
IIRC) to a higher level to reduce this problem. I'm thinking of a
different solution but i can't comment on it yet.
