Hi,
I'm trying to make a scenario where cities are part of the terrain. Basically, I've decided to get rid of arctic terrain and sub in my "city" terrain.
I can use any terrain from a mod (and edit it) and it works okay. However, when I try tto edit the original terrain 1 file I get grey triangles all throughout my map editor.
What do I do?
