Poor route movement
When you select a unit and click its destination, it does not move in a straight line. It may be looking for the shortest (least movement points) route and usually does a good job of finding it. However there are many times when the path between start and end has no intervening tiles with movement penalties; as shown in the picture below. Most of the time this is no big deal, however when you are trying to uncover the FOW and you unit takes a detour for no reason it can be a pain. I have seen it "zig-zag" from what should be a straight line by as many as 3 tiles causing me to back track.
Not a super big deal but it can piss off the player
. Suggest the router should only deviate from a straight line when it saves movement points
