Continuity mistake: In the parking garage, when they review Regina getting shot, a bullet wound can be seen on her back before the gun is fired. (00:37:12)
Continuity mistake: The way Regina is lying after being shot dead changes when Ravi and Liv are there, her arms are positioned differently and the body moves relative to the lines on the concrete floor. The knife is positioned differently too.
Other mistake: When Liv is pretending to be Major and texting Rita at the end of the episode, the text messages appear on the wrong side. Rita's messages should be on the left and Major's replies should be on the right.
