Aye, unfortunately. It takes about 10 to 30 attempts to join a game. If you don't join it usually just spits back and error saying "No connection to host". If you do manage to join you can play anything from 1 to 10 turns then it desync's and you're back to square one.
Doesnt sound great, I'm not starting my multiplayer campaign until saturday so hopefully it will be patched by then
