This is getting really frustrating. I live in a household with 2 high spec PCs on the same network (Core i7, 32GB memory, 1080 Ti and 1070Ti graphic cards) and a 50MB+ fibre connection (as Gal Civ doesn't offer a L:AN connection). Since 4.0 we just can't get the game to start a multiplayer campaign. Doesn't matter which computer tries to host the game, same result, set up the game, sync the player files and setup up the game. Hit start, watch the files transfer and then suddenly poof- doesn't work and get the message host computer disconnected.
Really frustrating as we just bought 2xRetribution DLcs for the game (as we are in Lockdown).
In terms of the 2 accounts. One person has GalCiv III and all the DLCs, the other is missing the 2 StarControl DLcs and that is it.
Seems to be a purely Gal Civ III problem. We have recently played multiplayer Warhammer II, Civ IV, Civ VI and Hearts of Iron IV without any problems.
