Awestruck. New Late Age game. (Game over, Atlantis wins)

You can't undo naitons set to AI. What you can do if you can find a sub is rollback the turn, install the sub, allow only the sub to submit their turn, and then force host, which returns the game to where it is now. But that of course is entirely the admin's decision as it involves a rollback, and so has a major warning attached to it. Otherwise the only real option is to continue as is.
