Ghost Passenger Ship Murder Case: File 1 - S2-E5
Continuity mistake: Kenmochi dumps two heavy bags on top of Kindaichi, then picks up two suitcases himself; a pink one in his right hand, a dark blue one in his left. When the second mate asks him the ticket, the two suitcases have swapped, and Kindaichi a moment later carries the heavy bags but also suitcases with the same colors as Kenmochi's, which he gave to the second mate...who is carrying a single suitcase, and grey. Later on, we see only those 2 bags and 2 colored suitcases, anything else vanished. (00:04:10)
