Did you save it in private before you published it, I did on the 'Shooting Game v.2.0' and it was only on for about 3 days (i spent maybe four days creating it on a private save), I doubt this happened to the create your own world because of what you said about "on, off, on, off", but it may have happened...
Just a note to everybody: Put your private save into a new save before publishing
I removed two saves made with the world template save, but did not remove the template. Pixel art isn't really permitted on the front page for a while unless it's just obscenely awesome.
