During a game tonight, (sorry i forgot to write down which number),
several cities were transferred from one allied player to another. 
In the process a galleon was also transferred, but the three riflemen
in it were not. When the galleon was moved, the riflemen stayed behind,
floating peacefully in mid-ocean.

I can see this situation creates some interesting issues as far as
fixing is concerned, since if the riflemen transfer with the
galleon it's an open question which city should end up owning them.
