What's going on with the Zone of Control (ZOC)? I know not all units have one, but even my cavalry don't seem to have one. Example: a line of mountains separating my land from the greeks. Built several fortress on the mountain tops and placed cavalry, riflemen and cannons in them (3 in each fortress, there are 3 fortresses). However the greeks just walk around them. Shouldn't they have to stop to take care of the cavalry? Also, I think it would be cool, if the range of your cannons increased by one if you put them on mountain tops.
