Problem with map editor.

[McGravin]

Does anyone know exactly how to add ruins and unique ruins to planets with the map editor?
When I do, the ruins icon and text show up on the planet window, but nothing happens if the planet is colonized.

When the map editor generates a random map, planets with ruins show them as the "Combat Movement" ability. This makes no sense, and you can't set a planetary ability to Combat Movement, anyway.
