I charged one of the beach collections that gives you the sandwich and rods. I then went into my inventory and used all my sandwiches and all the rods without remembering that the rods completely restore strength. So, mad at myself I attempt to visit a friend that is leveled in the 100s and the game crashes ( it always crashes on me if I directly try to visit very high level friends). Upon reentering the game I see that my energy is what it once was. I go to inventory and look! My rods and sandwiches have reappeared and my strength is what it was before!
If you make a mistake using energy charms or by charging a collection, know how to purposefully crash the game and crash it. Reenter the game and see if the correction took place.
