I kept getting the error "Failed to Cost, try again" over and over and over trying to use spirit stones on the novel "I really am a super star" when I looked at my profile, it now shows the cost and loss of spirit stones for every single time I clicked . And the worst part? Even though I lost all those stones I still wasn't allowed to read the latest chapter!. You can look at my spirit stone history under my profile for the evidence and proof.
