Revealing mistake: One of the party guests opens the door of the fridge and you can see behind the set instead of looking into the fridge. (00:32:40)
Continuity mistake: When Higgins and Del Haynes leave the house Higgins is wearing his camo vest and hat, which he wears throughout the episode until the end. Though the style of his hat and vest remain the same, the actual camouflage pattern on both the hat and vest changes. There are two different hats and three different vests. The changes even occur between shots, such as during the scene at the end when Higgins returns to the estate.
