I was playing a game with a friend and doing really well, but my friend got annoyed with his apparently bad city placement and did not want to continue the game. So I figured I would just continue the game as a single player game, something I had often done in Civ V. But so far, I have been unsuccessful. Upon loading the game, I cannot replace my friends slot with an AI player and can therefore not start the game. Has anyone else found themselves in this situation? Is there a workaround? Thanks.
