i've noticed this too. "fog of war" updates only take place it seems when a ship is selected or moves (with autopilot). i've noticed this when using the cheat to remove the for of war, planets and stars become visible but the fog stays until i select a ship. i've also noticed the mini-map won't update until i select a ship. the newest version might fix it...

Ya the Fog in this game needs some more work. For instance once you've seen a planet or starbase, you forever know it's status. IE what's in orbit on that planet, who owns it, or that the starbase was built/destroyed.

In early game, I'd agree with you completely. However, once you've reached mid game and a decent level of intelligence on a specific race, I can see having that info.

As far as a starbase being built/destroyed...once you know where it is, stellar cartography might be able to keep track of its existance/lack of.

In my current game the Iconians finally wiped out the Drengin. The starbases are gone, but I still have full sensors as if they were my starbases....and still existed. Since I also have Eyes of the Universe, this is a considerable amount of territory.
