hi, i have weird problem. i'm on router but all ports are open so people can easily join me in standart game (patch 1.61). but if i host game in any of mods ( including the default ones such as AmericanRevolution, for example ) some people don't see me and can't join but other can! Those others who CAN'T join are not on router and easely join me if I host game in 1.61! why it happens?
