I didn't know there was a thinking time for the AI, it usually moves instantly. I don't know how to set the thinking time either, if there is a way to set it.
Something else that might help are the 3 games which my friend and I tried creating to solve the problem. We even tried changing the map at one point (we thought maybe the AI was bugged the USA map). These are the games:https://www.warlight.net/MultiPlayer?GameID=7728505
At the time this was posted, all maps had over an hour of wait time for the AI to move.
