There is a sync issue forsure.
My fix is - if your using mod stay in game, the other player needs to leave and rejoin a couple times or wait till mod player had their field full. Then have the other player rejoin and they will see the same board as the mod player.
That gives the other player time now to build and do stuff which keeps the game in sync.
Also no mouse lib.
Other then that it works fine expect on note 9
