As I just finished a Dark Crystal I can say this issue doesn't exist on mobile. (At least for me)

Potential solution may be trying to finish it on mobile if you have the option and don't want to spend gems or wait for SP.

I'll build another crystal on the PC and let you know in 6 hours if this issue persists and if mobile solves it.
