Its have been bothering me sometime now that after finishing a chapter and get like 21/21 stars. A chest would appear at the bottom right corner of the screen and give you a reward for having a perfect score. After claiming those rewards, the chest it just stand there and doesn't disappear. Is it possible to remove it after you claim the reward? Like I say before, it bother me very much seeing those chest open and just be there, I don't really see the point of it being there when there's not any use to it.
