I'm playing Lithuania and one of the victory conditions is to kill the Teutonic order. Playing on M/M. After the two stacks of the Teutonic order appeared they marched to Kiev and they took it but it looked like they lost one of the generals (the heir). I went there with an army and managed to destroy the stack outside then city, the faction leader of the Teutonic order died in that battle. So the order had no generals left but it was still alive.
I went on to seige Kiev and took the city, no survivers.
There are no units and generals left but the order still seems to exist. They are first in the money rankings.
How can I win this campaign when the Teutonic order are non-existent anymore but the victory condition isn't fullfilled?
