Continuity mistake: When Sarek enters the banquet room to take his medication, the Tellarite sitting at the table holds a glass in his right hand. In all the full shots with Sarek in the foreground, the glass switches to the Tellarite's left hand. In all the close-ups of him, it's back in his right again. (00:14:50)
Continuity mistake: During the fight with the Andorian Kirk was stabbed in his lower kidney region, he even holds his hand there to stop the bleeding. In sickbay later on, he has a bandage around his chest and McCoy says he has a punctured lung. (00:28:30)
Continuity mistake: Just before Kirk kicks his attacker for the final time during the fight in the corridor, the Andorian picks the knife up off the deck with his left hand. In the very next shot, the knife has instantly switched to his right hand. (00:28:30)
Continuity mistake: After their life threatening surgery, Spock and Sarek somehow manage to switch beds between being in surgery and recovering. (00:45:00)
Continuity mistake: In one scene the Enterprise's phasers were pink instead of blue.
Continuity mistake: An Orion spy (disguised as an Andorian) attacks Captain Kirk in the corridor on Deck 5 and plainly stabs Kirk in the back on the right side. As he staggers to his feet, Kirk first reaches to the wound with his right hand, indicating that it is, indeed, on the right side of his back. He then reaches far across his back with his left hand to touch the wound, and we see blood on the back of his hand (but not on his sleeve). So, it is visually established that the wound is on the right side of his back. But, a few moments later in SickBay, Dr. McCoy announces that Kirk's wound is a "puncture to the left lung." Then, later in the episode, Kirk his holding his left arm as though he is suffering pain on the left side.
Continuity mistake: In sick bay, close ups of Sarek show him sitting up at a 90 degree angle, but the long shots show him reclining at a 45 degree angle as the shots cut away and back.
Continuity mistake: In the reception room, Amanda's glass goes from 1/4 filled after McCoy poured more, to over 3/4 full without his adding more.
Answer: After causing Norman to overload, all of the other androids shut down. The same could be said for the androids on the Enterprise.
