Thank you for being patient with us! 

We've fixed the issues at hand with the events:

Xespa's Prize Shop is now working properly. 

In addition, the Ritual Chamber puzzle for the Quest should now be visible to play for those who saw nothing on that page.  

Find the Feast's Prize Shop is currently still experiencing some problems. We appreciate your patience while we continue to work on this.

To clarify some confusion about playing the Quest: 

It is intended that each time you use a turn to solve the Ritual Chamber puzzle, any carved crystal skulls that do not stick will shatter and be destroyed.
