I was working on level 4432. I had bought $11.97 worth in coins to complete it. I used a hammer to rid the waffle that was in the way and then the last acorn disappeared and never returned to the board. See attached picture. I played it to the last move and then it ended saying that I didn't win the level. Please either refund my money or allow me to pass this level. The acorn never came back on the board.
