Chloe's hair style changes several times during her topless scene.
At the end, when Mandy starts the Jeep to leave, her arms and the backs of her hands are covered in muck, yet when she'said shown driving away immediately after, they're clean.
The back of Mandy Lanes legs were covered in mud when she first gets up after falling in the mud pit. In the next scene her legs are clean.
Towards the end when Mandy sits on the ground, the blood covering her hands is dry and beginning to crack and peel off. But moments later? when she stands up, the blood is clearly wet and shining in the sunlight.
Just after the ranch house lights cut out and Mandy gets up from the couch to find candles, Jake's arm jumps from down to up along the back of the couch, as different takes were edited together.
A flashback shows Garth putting the cows down with his rifle, but this would never work--the loud noise of the first shot and smell of the blood would cause the remaining cows in the pen to panic and potentially trample the fences. Plus, depending on what they were sick with, culling and burying them locally may have been illegal.
