No towers to get rid of fog of war on maps

Just got to maps and had three towers that I completed. Now have no more towers left to continue removing the fog of war. Has anyone seen this?

Fog of War is removed in large chunks by towers, but you can still remove fog in small sections by traveling towards the fog in the direction of whatever direction you aim or towards things you can see at the edge of the fog. Once you do find another tower, then it will remove another large chunk of fog.
