Okay, this is pretty embarrassing, but I just downloaded EoS, and I can't figure out how to advance a turn. I have given units orders, and then clicked on "Submit Orders." But nothing happens. I see a message that indicates that I have submitted orders, but that none of the AI players have. I am able to Unsubmit Orders if I wish. The game manual seems pretty useless, as I didn't see a section that explains basic mechanics of the user interface. Any basic instruction on how to just get the game moving forward would be appreciated.
