Getting back moonstones

Does anyone know if its possible to get moonstones back? Some how my daughter "accidentally" bought the premium stuff for the star path which cannot be completed because the duties are gone. How do I retrieve that ? I wasn't in the room she's 4. Lol she usually doesn't spend them without asking so idk what happened but she lost like 6k moonstones and i can't even see what she bought as well as the premium choices. Star path
