We are playing CnC for a week on LAN at our office. We play only with MAC laptops. CnC runs okay most of the time, but we want to play TS. We only get it up and running if we choose "play online" > "lan" and then start a game, but there is always within 5 minutes someone who seems to have a bad connection or something and the entire game crashes. When I kick that player, the game continues, but then another player will have a "bad connection" and the game freezes again... We tried playing a skirmish game, but in that lobby you cannot start a lan-game, just an offline game it seems... What should we do?
