That army is stuck in the rice field bulding somehow. That is not my fault though, but of the original maker. It is possible to put the starting armies elsewhere I believe, I just don't know how to do it. You should tell that to uanime5. As for the fog of war, there is an army select button bellow the minimap (the two crossed swords), just select an army inside a town and move it outside, that will reveal the map.
