- A not very noticeable goof is that when they show both Liv and Maddie you have to stay on your half of the screen, if you don't, you'll disappear. So Liv's purse accidentally crossed over the line and the corner of it disappeared. Also when she hugs Johnny, her leg goes over the line.
- Due to this, the ground at one point in the first scene looks weird because the cracks in the ground don't line up.
