Revealing mistake: "Alan a Dale": Lady Mildred rides side-saddle. But when Gisburne gallops away with her, some shots reveal that the stunt woman riding the fast-moving horse is astride it full straddle. Her skirt is blown back just enough to see a brief glimpse of the stunt rider's real leg on the horse's right, and the fake pair of legs in side-saddle position on its left. For just a moment, the lady appears to have three legs. (00:20:00)
Continuity mistake: Season 19, Episode 159. When Des Taviner flips and drives the area car wildly around an industrial estate and into a gas storage facility, you can see that during the sequence the Vauxhall Vectra he is driving starts off as a Y registration, then changes for several shots to a P registration, and then finally back to a Y registration when it blows up inside the building.

Episode #1.1 - S1-E1
Continuity mistake: Episode 1 - When the commissioner kisses his wife at the beginning of the first episode, he is holding the holstered gun in his left hand and his ID in the right hand. That's in the first shot, because his daughter enters the room bringing coffee, and now the two items swapped hand. (00:05:10)
Visible crew/equipment: Near the beginning as the two men are pulling up in the field with the goats, there is a black screen reflected in the window of the truck. It looks like a block to keep the sun out of the shot.
A Case of Sour Grapes - S1-E14
Other mistake: There is a sour bottle of wine that Jack and EZ taste in the kitchen - Jack throws the bottle in the sink and breaks it before Vicky and Mr. Bradford enter the kitchen and have a chance to taste it.
