Thats not my problem. I understood this. There are other occasions where it just doesn't seem to be right.Their is a type of fort that does not have zone of control. All Capital get a free fort. To counteract opms from being a pain with zone of control they removed the zone of control from default capital forts. You have to upgrade the fort in the capital in order to get zone of control in them.
Guess I just have to get my hands on it to figure it out.
