In my recent game with the 1.6 Insiders build for June 12, there are ships and structures that aren’t mine in my area of influence. Sometimes they are visible. Sometimes they are invisible. There is an option in Advanced Settings to have no FOW in my territory.  My territory means in my area of influence. This means that everything in my area of influence should always be visible.

When some of the foreign objects in my area of influence become invisible, it is because they are outside the area that is visible to my ships or planets or starbases. With the reduced base sensor range in Supernova, it is more likely that foreign objects will be outside the area that is visible to my ships and planets and starbases.

The problem is that the foreign objects should still be visible because they are in my area of influence. Something is wrong here.

I have found that the invisibility only happens after loading a save that I made. It doesn’t happen when loading a save the game made. The saves the game makes are the autosaves. They are made at the beginning of a turn. It doesn’t matter when I make a save. The invisibility only and always occurs when I load a save I made. After going to the next turn, the invisible foreign objects become visible and everything is normal.

Here is a screenshot made after loading an autosave the game made at the start of turn 200.

Here is the same screenshot showing where foreign objects are.

The objects in the areas marked in blue will become invisible. The objects in the areas marked in red will stay visible because they are close to some of my planets or ships, so they can be seen.

Here is a screenshot made after I loaded the autosave, saved the game, then loaded the save I just made.
Everything in the blue areas is missing, and everything in the red areas is still visible.

The autosave that starts all this is available here.

Load the save. You will be asked to load an Erector. You can load it or cancel – it doesn’t matter. Verify that all the foreign objects can be seen.

Make a manual save by whatever method you prefer. Load that save. Notice how many foreign objects are now invisible. Go through what is needed to get through the turn. When finished, go to the next turn. All the invisible objects are now visible.

For more evidence, save the game again, load that save and see how many foreign objects are now invisible.
