Is there a way to get rid of that ugly rubble left after a city is destroyed in Play the World? There was no rubble in the original Civ3. I know the rubble doesn't actually do anything -- the ground is still as productive as normal, you can rebuild on top of it, and all that -- but it just looks ugly and mars the cleanness of the rest of my land. Besides using a scenario or something that remaps all of the graphics, is there a way to get rid of it?
