The command buttons have an invisible character that you have to delete, after clicking on the command button you want from the drop-down list, select the end of the text and press backspace, no characters should be deleted, but if you press ok you will see that world builder will say that the command button doesn't exist, ignore, it's a world builder error, if world builder says the command button exists it wont work in game, it will only work if you delete the invisible character that's at the end of the text of every command buttons. As for the reveals, you need to have permanent reveals if you want the players to be able to always see the area revealed, and the players are named as "playerX" not "player_X" (player0, player1 for example).
