Continuity mistake: The father of Alex is wearing a red scarf in the shot where Spencer and fridge are in front of his house. From another angle when Bethany and her mom see them from the car he's not wearing the red scarf.
Character mistake: When Alex Vreek's father wakes him up to show him the board game, he knocks on the door and yells Tim or Jim, not Alex.
Suggested correction: He says "Hey, kiddo."
Suggested correction: Mr Vreeke shows up speaking to Spencer without a scarf, when it shows him through Bethany's mom's car window, he is wearing one. It goes back to him and Spencer and the scarf is gone again.
