Shadow Glitch?Bug?

http://i7.lbp.me/img/ft/57709fb603e8...9484340a67.jpg
This is a glitch i have been having for quite some time now. It keeps coming at random times when I'm working on a level and it happens in every level on my moon. I dont know if its unique to me or if anyone else is getting it, but if you are, do you know a fix? Do you know how to report an error or glitch/bug like this to Mm?

Thanks all.

did you use the move tool while creating? that happens to me, but only when i use move stuff

[EDIT] btw that looks like a really nice level...
