Hiding the fleet, short save

Suggested by: Frensis ()
part of the fleet usually stands on the moon. in the event of espionage, information about this fleet will become known . there are proposedegie do recognition of espionage and raising part of the fleet in the save to hide information about the fleet. and you can also make a short save for example for an hour on 2 for a short absence, it will look more like a human game.
Awaiting approval
