When I start a game under certain conditions, the world map is entirely blank. This seems to happen more often if I am using a custom soveriegn, although I am not sure yet. This keeps happening until I exit and restart the game.

EDIT: O.K. Some more information. It appears that the game is pulling in old info from the last time I played with this soveriegn. The screenshot comes from a new game I started after I had won the last game. If you look at the information panel at the bottom of the sceen, it shows that I have two settlements and am researching civilization. This was the condition I was at when I won the last game, but it should no longer be the case since I had just started a new one.
