At about 46:16, Joseph enjoys iced tea. He drinks and lowers his glass, but when the camera cuts to a wider shot, the glass is back to his lips.
At around 2:30 into the movie, a man gets off the elevator at the 1st floor, as shown on the elevator, but walks into a windowed conference room with a view of a city showing that he is on a much higher floor.
(Lauren Swickard) Callie has a double barrel shotgun that she uses to point at Connor (Gunnar Anderson) as he surprises her when he walks in. As she lifts up the shotgun you hear a cocking sound when in fact with double barrel shotguns there is no fore-end and would not produce that type of sound when loaded.
Callie can be seen multiple times wearing shorts and tanktops; however, the weather in this area around December would make it too cold for such attire.
