Gates???

Everytime I am in a seige battle and i move my men from one gate to another the gates stay open???? Does this happen to anyone esle?

It can happen if a spy has opened the gates. Otherwise the gates only open for the faction that possesses them. Are you sure that you don't have a unit stuck in the gate - even one or two troops will do it?

yes i am sure. And no there is not a spy.
