when collected 7 stars, I get reward in form of boosters. A few times I have gotten a red circle with a white circled arrow inside. It's not the infinite symbol, but an arrow drawn inside the red frame, in shape of circle. I have no idea what that means....there is no where to choose to use it, I have never even it anywhere else but when it's showed in the reward chest. What does it do...I assume something happens automatically with that booster...since it's now where to be found ingame?
