The Prison Prep School Murder Case File 3 - S1-E12
Other mistake: During the science lesson about DNA, the teacher shows the double helix structure. One wonders how could he draw it using 3 colors since he has just white chalk at his disposal. The figure disappears a moment later when he starts giving out the test papers. (00:06:30)
Inspector Kenmochi the Murderer File 3 - S1-E21
Audio problem: Kindaichi is listening to the recording of the phone call a couple times over; however he does not listen to it in a loop, but rather the file shows up as lasting 52 seconds, with the call being just a handful of seconds. On top of that, when he listens to it again in front of the building, the timestamps don't match.
