Plot hole: When Wolf and Tony find Virginia in the Huntsman's tree house, she tells them that he chained her up, so she can't go downstairs and open the door from the inside. However, after Wolf climbs her hair and enters through the window, the two of them walk down the stairs without any chains stopping her. They couldn't have cut her free with the magic ax because Tony was holding it, and he was downstairs by the door.
Other mistake: In the boat with the golden fish, the sign next to the fish says that you must stick your finger in the fish's mouth, then turn around until you "face south". Later, Tony sticks his finger in the fish's mouth and doesn't make any turning motion, yet he still gets the golden touch ability.
Other mistake: After Virginia wins the mirror in the shepherdess competition, she and Tony are in the barn and they hear Sally screaming. Immediately after her screams are heard, a man runs into town and says that she has been murdered. Between the screams and the man announcing the murder, there wasn't enough time for Sally to have screamed at her grandfather, been killed by him, and then been discovered dead.
Audio problem: During the shepherdess competition, when Sally says that Virginia doesn't have a dog, there is a shot of Sally while she is still saying the words, but her lips aren't moving. She just makes a small smile.
