I've change the rules.ini in my game e share the files spawn.xpd and spawnam.xpd to my friends, for us play online using de cncnet but only room for us, my friends and I. Yeasterday two friends played against eatch other  and 3 hours later the game of both of them go down for strange reasons and today one of them cant log in cncnet, dont go further in the conection, just a message that gonna take less than 1 minute to conect and never happends.
 

Both of them get ban? Thanks
