The Death March of Young Kindaichi File 3 - S2-E3
Other mistake: Kindaichi in this episode watches the footage of the events in the previous episode from Saki's handicam. Saki was running with the camera and the camera was jerking up and down a whole lot in those animations, but here the motion is very subtle. Li also was standing facing straight away from the door, parallel to it, but here he's more turned to the left.

Other mistake: When Kindaichi rushes to Longtao's rescue, he is not carrying the flashlight with him. He's in a deep cave bunker with no light at all (plot point mere moments earlier), he should be blind as a bat. In the following episode he even searches for clues in the cave, again without the light.

Other mistake: The two survivors from 18 years prior approach the building with nothing on their person, then suddenly Matsuoka has a flashlight, which he gives to Shinomiya as he goes inside alone. Kindaichi and Longtao arrive, completely unprepared to any dungeon crawling, and the three of them go in with yet another flashlight. (00:13:50)
The Death March of Young Kindaichi File 1 - S2-E1
Other mistake: During this episode and the next 4 of this story arc, the signs of the stores in Hong Kong are recycled from the first episode of the series. Hong Kong is a pretty big city, the odds of Kindaichi (who is not staying at the same hotel nor dealing with anything related to the first case) just happening to be in the same nondescript streets with the "Ocean Guest House" are astronomically low.
