Episode #2.7 - S2-E7
Continuity mistake: The protagonists break inside the the SMDA building. Richard is checking out a folder placed in front of a pile of papers. He turns towards Camille because of a sound she makes, and in this new shot his hands are in the pile, not the folder. (00:20:05)
Episode #2.7 - S2-E7
Continuity mistake: Richard takes the flyer off the book, closes it and hands it to Camille. In the next shot though the book is open. Even more evident, a few seconds later Camille later mentions a local politician; Richard lowers the book, but it's up again for the close-up. (00:17:30)
Episode #2.7 - S2-E7
Continuity mistake: When Richard notes that one hour elapsed, everyone's position is the same as the camera angle switches, except Dwayne who first is checking his watch, then he's just pointing at 'Chief' Poole. (00:14:35)
Episode #2.7 - S2-E7
Continuity mistake: After the conversation with the professor, Richard gives a rather lackluster pep talk to Fidel saying it's "possible" that he will pass the exam. During this small scene, Dwayne's movement in the background change inconsistently between shots as he is scribbling and putting away his pad multiple times. (00:10:50)
Episode #2.7 - S2-E7
Continuity mistake: Professor King's book changes position in Richard's hand several times between shots - it also goes from open to closed when Richard boasts about his 'demon proof-reader' skills. (00:10:10)
Episode #2.7 - S2-E7
Other mistake: Richard does not possess psychic powers, but he grabs from the shelf the one book that is a key plot point; the book is amongst many others in a bookcase full of texts. It does not stick out literally or figuratively in any way and most importantly, it does not feature the professor's name on the spine - that is probably where the issue lies; manufacturing the prop they did not leave any clue about the professor that Richard could have picked up - the name is merely on the front and back. (00:09:50)
Episode #2.7 - S2-E7
Continuity mistake: DS Camille Bordey's hand is in the foreground holding the pen when Leo Downs' voice says that he could "blow the whole department apart", but she lowered that hand in the previous shot, and in the next it is properly down. (00:06:30)
Episode #2.7 - S2-E7
Continuity mistake: When the dean plays Leo Downs' message for Camille, in close-up her hand is on the organizer; it was the whole sleeve in the previous angle. Not just that; the flyer underneath the rubber band of the file board is in a different position. (00:06:25)
Episode #2.7 - S2-E7
Continuity mistake: Dwayne walks towards Poole and Bordey introducing Judy Hearst, the dean. She removes her bag from her shoulder and puts it on the lawn twice in two shots about 5 seconds apart. (00:04:40)
Episode #2.7 - S2-E7
Continuity mistake: Inspecting the crime scene, after Richard conjectures foul play Camille asks "So we've found the body before it was intended to be found?" She shrugs and holds her hands elbow-high, but they are thigh-high at the cut. (00:04:20)
Episode #2.7 - S2-E7
Continuity mistake: When Leo asks Damon to swap, he lowers the clipboard he was holding rather high all of a sudden, and in the next shot it's high again. (00:00:45)
Episode #2.6 - S2-E6
Character mistake: DI Richard Poole does not correct Officer Fidel Best properly; he says that the case he has in mind is "Makin v Attorney General for New South Wales, 1894", but it's actually 1893. (00:07:10)
Episode #2.6 - S2-E6
Continuity mistake: Camille bags the phone holding the lid with the left hand in the wide shot when the action begins, but her hand is much lower in the following shot when it ends. (00:06:25)
Episode #2.6 - S2-E6
Continuity mistake: The bottle of Tensel in front of the douchy patron at Catherine's bar changes rotation between shots. (00:01:20)
Episode #2.5 - S2-E5
Continuity mistake: The detectives realise that the backup singer is the wife of the boss. When Camille asks him that, she folds her arms, but she has her arms down her sides and folds them again in the following shot. (00:20:30)
Episode #2.5 - S2-E5
Continuity mistake: At the start of the denouement, Richard says "during what was to be her final number." Both Camille and the boat owner are in a slightly different pose between takes (he distances his fist from his mouth, she has her finger in front of her lips, a closed fist in the next shot). (00:43:05)
Episode #2.5 - S2-E5
Revealing mistake: When Ben Miller asks for the forensics report on the oyster and shot glass, the report has egregious spelling mistakes ("Specimin" instead of Specimen) and shows the victim testing positive for Oxycodone rather than strychnine! For the record, it is an entirely different lab test (a real one, with 'specimen' spelt correctly) done for a patient under prescription medications (morphine, oxycodone and benadryl) and its date is inconsistent with every other episode (it's a 03/19/2010 document and in the first season it was established the year was 2011), but these last details can be noticed only if you freeze-frame. (00:42:00)
Episode #2.5 - S2-E5
Continuity mistake: After Dwayne kicks a sleepy Fidel off his chair and they go get the bootlegger, Richard is on his own with Camille. During the scene, the innermost shoulder strap of Sara Martins' top is either perfectly attached or apart from the others depending on the angle. (00:37:55)
Episode #2.5 - S2-E5
Continuity mistake: When Camille concedes that Richard's babbling is "better than the dog story", her arms change position around her legs through a mid-sentence cut. Same when he tells her that they found strychnine in the bottle. (00:26:10)
Episode #2.5 - S2-E5
Continuity mistake: When Dwayne talks to the guy who is not a 'rocket surgeon', he sighs and slumps back on the chair, but his left arm stays on the notepad. Cut, and his arm is off the table entirely. (00:12:10)
Answer: There's probably no particular reason. Sets and props on long-running TV shows often change as needed and for various reasons throughout a series run.
