Ok, so in the last week, I've tried playing 4 online games with a friend and 3 of them desynced within about the 1st hour of play. The other one crashed and then the autosave we loaded from desynced.
Entrenchment and Vanilla Sins both work fine for us and we haven't experienced any problems like this in the last few months with them, just Diplomacy.
I was wondering if anyone else is experiencing these problems and if the Devs are working up a patch?
I will say, though, that Diplomacy is another great expansion to an already great game and I congratulate Stardock/Ironclad on their extraordinary games + customer support.
-Thanks
