Now I just build small ships and have them sent to a forward Battlestation to be moved or sent into battle. Now when 4 small ships get there I make a Fleet (Due to Logisic numbers). How ever some times I get a 0 Fleet that I can't use or delete. But the small ships are still not grouped until I move them off the Battlestation then group them. Now to clearify 0 Fleet. In the mini screen to the bottem middle of the screen you can see all the ships,bases and others on that spot. when you click Create Fleet I am getting a empty box 0 Fleet that never goes away. How ever this only happens on the Battlestations and Starbases square or spot.
So now I have a Battlestation with about 8 empty Fleets that only goes away if the base is destroyed or sold off.
