Forty Years from Sand Island - S3-E17
Revealing mistake: After the savage beating, the two other prisoners go check out what happened inside the restroom. The take of Kirin Nakamura lying face down begins with the actor stretching his finger before he has to play corpse for a while not moving a muscle. (00:04:25)
Forty Years from Sand Island - S3-E17
Continuity mistake: In the flashback, the one who supports Mr. Nakamura's head does it with the thumb raised above a cone of shadow and clear of his chin in close-up, not matching the previous and following shot. (00:04:30)
Forty Years from Sand Island - S3-E17
Revealing mistake: Magnum usurped Higgins' desk while he's at the hospital. He is checking out of the article about Enoka running for Senate. If you look at the first article on the left, it begins with "The facts regarding the situation remain the same, state the authorities", the famous filler text that appears in dozens of props made by Earl Hayes Press. (00:16:35)

Continuity mistake: Magnum approaches the Nakamura house getting out of the car with light beige shoes. The young and pretty granddaughter of the deceased walks him around the corner, to her father. In the scene with Russell Nakamura, Nancy's Father, Magnum suddenly has dark brown moccasins, which you can see when he walks towards him and then away. And then when Nancy walks him back to his car, the beige shoes are back. (00:20:10)
Forty Years from Sand Island - S3-E17
Revealing mistake: When Magnum rolls slowly in pain after being hit by the first box, and then when he rolls quickly to 'avoid' the others, his lab coat appears to have protective padding; there's a rectangular shape sticking out. (00:21:25)
Forty Years from Sand Island - S3-E17
Continuity mistake: Magnum's wife makes him lie down again on the office couch. His tie runs down his left side with both ends when the camera is behind his head, one to the side and one straight in the other view. (00:23:20)
Forty Years from Sand Island - S3-E17
Continuity mistake: Magnum sits down with Saichi Goto leaving the girl on the pier. He asks him "what do you remember about 'em?", and holds his left hand with his right. Reverse shot and it's the other way around. (00:26:10)
Forty Years from Sand Island - S3-E17
Revealing mistake: When Higgins' wheelchair starts taking off and he cries "I say, MAGNUM!" you can see rise from the grass a thin line used to safely halt the chair when off camera. (00:28:05)
Forty Years from Sand Island - S3-E17
Other mistake: Hank Palmer appears in the closing credits as "Hank Sorenso", but his last name is pronounced by everyone (and logically so) as "Sorenson", and Rick says his first name is Fred. (00:31:00 - 00:48:00)
Forty Years from Sand Island - S3-E17
Continuity mistake: Nancy Nakamura steps away from Magnum telling him she "did not have to decide." Her hair is fully combed back. She is briefly out of frame, and Magnum walks back to her without her moving, but her hair is now cascading all over her shoulders. (00:39:00)
Forty Years from Sand Island - S3-E17
Continuity mistake: In the confrontation at the pier at the end, wind blows through Andy's hair more when he is shot from behind, less from the front. (00:40:30)
Forty Years from Sand Island - S3-E17
Plot hole: The culprit is in cahoots with the man that Magnum is trying to expose as WWII war criminal, and fears nothing from him, as he even explains to Magnum later; in fact he is his goose with the golden eggs. Yet he, a politician, kills his guy in broad daylight, for no reason, running the risk not only to be caught red-handed, but also more logically to be linked to him due to the investigations that will unveil the deceased as one of his major supporters. Instead, he does not touch Magnum, someone he has no connections with and tons of potential enemies. Let's not forget that the main motive that pushes Magnum to investigate is his assumption that someone wanted to kill Higgins, which is not the case, and the culprit knows that.
