Issue With Conquest Victory

I am playing a game where I have captured every world, but the game says that there is one other civilization still alive.  It turns out that this is because that civilization still has a colony ship somewhere in the universe.  I have included 4 screen snapshots below:

• The first one shows the size of the universe
• The second one shows that there is another civilization that is still alive
• The third one shows where the colony ship is (but you can't see it!)
• The fourth one zooms-in so that you can see the colony ship without it being covered by the banner containing the world name

I spent a lot of time playing "Where's Waldo" trying to find this colony ship hiding under the world name banner.  There should be a way to find any ship owned by a civilization to avoid this kind of unpleasant endgame experience.

 

Sorry, the screen snapshots were there when I originally posted this message, but for some reason they disappeared.  Since I continued playing the game I cannot recreate them.

If I knew how to upload a saved game, I could upload the save I created with the hidden colony ship.
