While crossing the street at an intersection in the city, the lead characters walk as a gray SUV passes through the intersection behind them, turning left, but then vanishes. As the couple continue toward the opposite side of the street, the same gray SUV passes through the intersection behind them again, same direction. This time, the scene cuts before the SUV can vanish while turning left.
When Ashley and Lily are sitting in the diner, after a making a Christmas log, the position of the lemon slice on top of Ashley's glass keeps changing position while they are talking.
When Ashley and her mom were making the Yule log cake, they had a baking pan which they lined with parchment paper. After they baked it, the next step was to roll it into what would look like a log. However, they didn't take out the paper when they rolled it. So they decorated it beautifully to look just like a log, but it was completely enclosed with cooking paper in each layer.
