Moving between servers, I expected more broken scripts. Turns out I found most of the broken ones trying to upload this image. They are all in my administration area. (uploading checking sizes and such.) Hopefully you can see this.
This one has been sitting unfinished for a year, because the gray blast wave didn't like mixing with the fire, and kept crashing the computer. I figured out it would render once per loading of the image, only crashing the second attempt. So I reloaded after each test render, which let me finish.
