I think the problem is, that Gimp can not work with effects + layer masks on "groups" i created for each "type" of crystal a group which holds all colors for the same group, then i only needed to add the mask once. tomorrow i will try to fix the image.
I have added a transparent png map. I also got the error in gimp and couldn't fix it. i tried some versions but none of them worked.
