Tasharen Fog of War - Ring left in fog after revealer leaves

[Anselm]

I've run in to this odd issue, whenever a revealer leaves an area it leaves a small trail of lighter fog behind it. This happens when a revealer moves through an area, and when it is set as not active anymore. Here's an image of the issue



As you can see, around the planet there is a lighter area left after I toggle off the revealer. Any ideas why this may happen and how I can fix it?

FOW has 3 states: unexplored, explored, and visible. When you explore an area and then leave it, its state never returns to "unexplored", but will remain "explored".

If you don't like it, change the "explored" color to match your "unexplored" color.
