Forty Years from Sand Island - S3-E17
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)

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)
