A side note- this clears up once a ship with sensors touches the affected area. Some issue with the FoW code that uses influence area?
You are right, of course, but it's yet another bug that SD has not fixed. SD tends, it seems, to only fix things that make them money. This game is riddled with sloppy code.
Once upon a time, GC was one of the best games on the market. Now it's a mess,
