I finally tried the modpack with my friend with whom I used to play multiplayer, because of desyncs and poor vanilla game. We're amazed, how good is it again to play multi, but with this amazing mod.
We were playing for about 6h and no desyncs, I mean - we didn't have to host a new game and load save like when we played vanilla game. But once game freezed and loading screen (with Civ I played) appeared, like the game refreshed itself - is it intended or it's some kind of bug? It's no problem for us, better this, than hosting game and loading save. It happened several more times when we were at war with AIs. But after first "loading screen", my friend's Great Writer disappeared.
Is it any way to host a game with this modpack and Communitas map script? I couldn't find it.
My friend has polish version of CivV, some things that mod changed are in english, but some things not. F.e., Social Policies descriptions are polish vanilla ones. Is there any way to force the mod to display things that were changed in english? Or he just have to download english version of CivV?
Is there anyone who knows how long would take translating this mod?

Anyone tried?
Oh, and we downloaded V1/20 and the settigns: map Continents, small, 6 players (3 teams; 1 team consists of 2 players), standard speed.
