Well I`ve actually managed to wipe out all the Geisha with some hardcore Ninja`s. I can now train geisha of my own, however I don`t want to win the campaign like that. I have encountered a problem though. Hojo have attacked me in Kawachi, it`s a massive battle, over 5,000 of them vs over 2,000 of mine. When I try to command the defence I get an error message "Shog_CPP" and the game crashes to desktop. I have tried reloading and going again but I get the same error message. I am willing to try to Auto resolve if I have no other option to keep the campaign running but I would rather not.
