I've got a major irritant with the blocking of armies, the initial 'green' movement area shows another army with red ring around it where you can't go without getting held next to that army. But the 'green' area shows that you can get to a point behind the army that you wish to go to. Then the path that the army choses when you order it to that point takes it into the army red ring :(

Crusades moving by land now are a terrible chore ;(
