Walkthrough for the "Tribes of the East" expansion.

Hello everyone! Your forum helped me when I was completing the mission "One Clan - One Khan." Now I'm stuck on the very last mission; I can't defeat Kujin's city. I read a bit here but couldn't find a solution. Maybe someone knows something? (Stopping her is not an option; she doesn't stop, and the second player only has one trapper, and the flying ship isn't arriving either.)
