Tried doing a jigsaw puzzle and put all the pieces on the board. The timer kept going and it looks like the game doesn't detect that the puzzle is finished. Anyone seeing this issue? The sliding puzzles worked without issue.

I can't get the achievement for all sliding puzzles. I completed all sliding puzzles, but there is no achievement, because after completing the penultimate jigsaw puzzle, a menu opens, and after completing the last jigsaw puzzle, a blank screen opens without a sliding puzzle, but with a timer...
