The Hong Kong Kowloon Treasure Murder Case File 1 - S1-E1
Other mistake: Throughout the episode, certain street signs ("Job&Piece", "Ocean Guest House") are used multiple times in different points of Hong Kong (for instance the establishing shot of the city, behind Kindaichi and his friends when they meet, during the bike chase).
Other mistake: In this episode, Hera's ears are shown for the first time thanks to her civilian disguise. As for all Twi'lek women, they're shaped like cones. However, they are too large to fit under the ear coverings of the pilot's cap she usually wears, when they've been shown on the few occasions she hasn't been wearing goggles or a pilot's visor.
