Odd Bug

I hit a real odd bug today. I was ready to scrap and upgrade one of my
fleets, so I park it in orbit around one of my worlds. In orbit are 3
fleets; my 1 12/12 fighter, my  40 12/12 fighters+colony ship, and my
allies 7 12/12 fighters+1 fleet. I go to the fleet management dialog to
split off the fighters for scraping and I notice in the right hand box
is a 1/1 scout that did not show up in the map screen. I think nothing
of it and split off the 40 fights, but when I return to the map screen,
they are gone! I am not too happy at this point, because that is most of
my metal. I also do not see that phantom scout in the map screen. So I
go back to the fleet dialog, and the scout still shows in the right hand
box, and the colony ship in the left. I tried adding the scout to the
colony's fleet, and it worked but the scout still showed in the left
box. So I added it again. Now I have 2 scouts with the colony ship and
the single scout still is in the left box. I kept adding scouts until I
got up to about 15. Then I split the fleet so the colony ship was in the
left box, and the 15 scouts in the right. Then I go back to the map
screen and now the colony ship and the 15 phantom scouts have
disappeared!. All that is in orbit is the ally's fleet. The fleet dialog
screen now shows a 1/1 scout in both the left and right box and you
cannot combine them.
