I don't have that problem either. The only problem I have with maps is around Garontor castle, that can be a focus point if at war with Aserai and you hold that castle. Most of the battles are close to the sea shore, one side right up against the water (mostly me).
I did fight one battle down the valley from Pen Cannoc, the battle map was exactly that - a river valley with the large town of Pen Cannoc on the hill top .. Beautiful !
