This has been an ongoing problem for me as well. This has been going on for weeks!!!
We appreciate you taking the time to post. We have forwarded the matter regarding the Element of the Day to the proper parties. Once we receive word back, we'll provide you with an update.
You can still get wish stones for doing other activities such as clicking on the snowmen (Nothing to see here) or activating the large element sanctuaries. The wish stones are random but can be collected within the game.
