Hi, I realize this is very much a newbie question, but I couldn't find anything by searching. So here's the question: I want to expand a lake in worldbuilder. I use the map mode/terrain/coast button, but wherever I click, Civ places some strange dark blue water. This looks very ugly. Am I doing anything wrong or is this the only way it works?

[edit] D'uh, it goes away on reload. Nvm :/

Use the ocean feature. That should do it.
