I generated about twenty 8K worlds with this, and none had installation_red_mesa, which is industrial zoned. I'm a complete noob, but I tried editing the skyscraper xmls for the mod to remove industrial zoning from them. That seemed to result in reverting back to having at best two skyscrapers per map, and still no Red Mesa (though I only fried a few maps like this.) Too bad, as I wanted more skyscrapers, but also Red Mesa because I've never played through it. At any rate, I was getting a dozen or more skyscrapers per map with the mod as is, so this will definitely get you the big buildings.
