While playing the final stage of the event, I experienced the bug where the shown number of available moves is wrong. I had zero moves remaining, but the game showed 12/15 remaining. I was 2 pieces away from completing the puizzle & unlocking the girl, so I sent the 2200 kobans for 5 additional moves. This set the displayed number of moves to 17, but the real number should've been 5. I completed the puzzle and received the girl. I then received a pop-up message saying that I was being logged off for cheating. After I logged back in, the puzzle was reset and the move counter was at 3.
