Have they given the AI more cheating knowledge? Played first game with the patch and Alexander declares war shortly after I refuse tribute. I had one city on the border undefended but with an archer on the way, I dispatched 2 additional units from my capital. He sends 1 axeman which gets there after the archer but before the reinforcements and takes the city, which I retake the next turn. Then he plops down 2 units from a galley on the opposite coast which is just enough to take that city again 1 turn before I can get reinforcements there. Just coincidence or are others seeing cheating?
