I was playing AGCEEP as Athens. I only have one province. A few years into the game my allies declare war on the Ottoman Empire and I decide to go along for the ride. I march my army north and begin a siege of Macedonia. While I'm doing this the Ottomans advance into Athens and lay siege. Their siege succeeds before mine does. About a month after this the game jumped out to the Victory Point summaries. What happened???? Why was the game over? And what did I do wrong to allow this to happen?
