Gameplay Bug Prevents Progress in Bonus Chapter – Dark Parables: Goldilocks and Fallen Star (Full) Review

When I added the strings to the musical instrument, the game still showed the instrument as a work in progress, and therefore it could not be used. This made the game unplayable, and you cannot restart the bonus chapter to try to reset the error.
