Has anyone else seen this challenge? It is the #3 Beach Club Blvd on ios- I am playing for the silver. I want to do the challenge with China Mystery, but that is not a symbol that China Mystery uses.... I tried a few hundred spins just to see what happens but it stays at 0%. Any thoughts on this one? I tried searching but it seems like it used to be a challenge that was 5x some symbol and no one references China Mystery so I think this must have happened after some type of update to the game.
