The shape is a blue/red crystal circle topped by a yellow crystal circle topped by a plain circle. I can get the two halves of the bottom layer and I can drop half a circle on the red and blue circles and then I can add a half layer of yellow crystal, but when I go to swap shapes (which worked on another shape I made) and the swapper just destroys all of the crystal and leaves just plain shapes which do me no good.
Any suggestions?
