It's an awesome tower - looks amazing, great rendering, etc.!!! But it grows like 15 times per skyline, and it grows like a weed as blade2k5 said. So I tried to delete it, but it doesn't work because my computer says "the file already exists in SimCity 4" so I destroyed all of them in my cities (which was around 8 or 9) but it still prevents me from deleting it. How do I delete it?????
