So I just got started.

In the beginners guide, it says that when  your energy drops to zero, you can go to "restore energy" and follow instructions to proceed. When I go to that page, there are colored buttons with the names of those colors, and right above that is an icon like an image failed to load. Clicking the colored buttons does nothing, and there are no instructions on how to proceed.

 Am I missing something here? What do I have to do to restore my energy?
