Event Bug - Puzzle Move Count Error

[Unoriginality]

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.
