Unfortunately this usually happens when the drawing was saved incorrectly, and can only be fixed if Nick flattens the image. :c
If you send me a PM with a link and description of the drawing I can forward the problem up to him so that he can see if there is anything he can do to help.
So sorry about the bad luck D:
Edit: He was able to restore it, yay!
