Mhh...that's interesting because there isn't any wish subtraction in the casino. So you should never loose wishes - the only expection is, using them in the chapel for gatcha. I will take a closer look and see how the behaviour could have occured.
I will update the chess minigame visual, no worries. The current state is there to give the player some variety for build endgame grinds. Since I didn't wanted to subject the player to playing the rythm game over and over again.
Is on purpose for this version!
Thank you for telling me all of this.
