Me and my brother are both playing the Rebellion Beta for the first time together. We just did three games in a row today. Every game, during the first 10 minutes some really weird stuff started happening like: "hey, why are you not colonizing that planet ?" "I did colonize it !" "Did not!" "Did too!"

With time it got worse and worse until it's unplayable.  I remember from vanilla SOASE, you would get "DESYNC WITH PLAYER X" messages but on rebellion we get nothing, the game just goes on.

And weirdest is: after one hour of play, with nearly everything being desynchronised, we could still see each others' real time ship movement !! Like "now I'm moving my fleet" "yeah I see that, you're moving it to this planet right ?" "yeah, all 30 of them" "wait I only see 10 of them"... etc...
