Small Graphics problem?

[jinif]

I noticed that when I loaded a settler onto a ship, and then moved the ship, the icon representing the settler turned into a worker. Although when I unloaded the settler, it was still a settler. I 've dowloaded the newest patch, and I was using the world map that "Marla" something had made, so maybe some of the rule chages affected it. Just want to know if anyone has had the same expirience.
