I don't know what that is Myrddraal, have you tried renaming the one in base as a test so the game can't find it? Your new map_heights.tga is named correctly? have you deleted the height.txt... er clutching at straws. So the game is loading but showing the map_heights.tga from base, but then when you edit a pixel from DJs in your campaign folder it goes wrong? In what way does it load badly?
