if this is correct then you should see a thumbnail, but nothing in the project EDIT: Oh, so editing this field won't break the glitch. Ok then. Time for explanation. Background doesn't update when you delete stuff from it, until you refresh the page. However saving before you refresh means that you save the 'glitched' background as the thumbnail. So this means you can put a cover in that nobody can easily copy, if you ever need something like that. Otherwise, kinda useless.
