Changing the terrain mask to 4194306, as Saint_Dude suggested, removed the Ovens.

Is there a good tutorial/manual on the map file format anywhere? I'd like to know why this happens. And if there are any other sites on the map.
A random map shouldn't have sites, as I understand it.

We could leave it in as a thematic feature, but it's a little more powerful than I'd like. I'd make a beeline for it if I started in that area.
