Visible crew/equipment: Boom mic is visible at the top of the screen as Hoss is about to give water to the gold thief they found nearly dead in the desert. (00:42:50 - 00:43:30)
Continuity mistake: A flashback episode set in the 1840s opens with Ben Cartwright as a first mate aboard a clipper ship. Rear-screen projection shows an ocean and a grey overcast sky. In a shot of the crew on the rigging and in the crow's nest, the sky is deep blue with a few white clouds.
Factual error: In a flashback episode set in the 1840s, Ben Cartwright and his former Captain are operating a ship's chandler business. A competitor accuses them of running a "flea market." That term is a translation of the French "marché aux puces" and did not enter the English language until 1922.
Factual error: Joe Cartwright gives a Raggedy Ann doll to a young woman named Annie. "Bonanza" is set in the late 1860s. The Raggedy Ann character was created by Johnny Gruelle in 1915.
Character mistake: Jamison Filmore reminds a steamboat captain that they were in prison together in "Cell 241." Five minutes later, he says they shared "214."
Continuity mistake: The sheriff of Morris Flats suspects Adam of being a bandit and puts him in jail. The window of Adam's cell has four vertical bars, but when the "knight" comes to talk to Adam from outside the cell window, the window has five vertical bars.
Continuity mistake: Laura Dayton is at a party at the Ponderosa but leaves and goes outside because she has a headache. Ben Cartwright's brother Will comes out and says he'll take her home via horse and buggy. It is night and the sky is dark, but when they reach Laura's house, it appears to be early evening. The sky is much lighter and the trees are casting long shadows on the ground.
Other mistake: Outside the Pine City marshal's office is a painted backdrop depicting some two-story blue-and-white buildings. The same backdrop is seen from the Virginia City saloon. It also appears in another town in the episode "The Legacy."
Continuity mistake: Adam and Joe are restraining Hoss while Ben gives him a ladleful of a thick white tonic for "spring fever." Joe has his right arm around Hoss' neck and is holding Hoss' mouth open with his left hand. As Hoss takes the tonic, a glob of it spills onto his left cheek. In the immediate close-up, the glob has vanished.
The Legacy - S5-E11
Other mistake: Adam stops at the Wild Horse Saloon in a nearby town, seeking information about a man who he mistakenly thinks has killed Ben. Outside the saloon is a painted backdrop depicting some two-story buildings. It is the same backdrop seen from the saloon in Virginia City.
Factual error: This episode is set in 1861. A little girl, Peggy Dayton, has a Raggedy Ann doll. Johnny Gruelle did not create the Raggedy Ann character until 1915.
The Guilty - S3-E23
Continuity mistake: Ben Cartwright agrees to meet a man at the land office at 9:00 the following morning but when Ben arrives at the office the next day, the time on the wall clock is 5:47. In a scene that takes place a few minutes later, the clock still says 5:47.

Visible crew/equipment: Two horses are tied to the hitching rail in front of the jail. In an interior shot, Lothario Larkin flings the jail door open and runs outside and to the right. The background is obviously a painted backdrop. It shows no horses, only the dusty street and a building on the opposite side. Larkin casts a shadow on the backdrop as he runs out.
The Hunter - S14-E15
Visible crew/equipment: Joe, wearing a green jacket, is seen from behind as he talks to a rancher. A studio light is obviously being used. A shadow, probably of a stagehand, passes across Joe's jacket.
Audio problem: Early in the morning, as Joe enters the living room, the grandfather clock chimes three times but the time shown on the clock is 2:57.
The Sound of Sadness - S14-E10
Visible crew/equipment: In the foreground, a teakettle on a stove starts whistling. In the background, Jonathan May lights a lantern and walks toward the stove. At the exact moment he lights the lantern, a studio light is turned on and its reflection is visible on the kettle. In addition, the light illuminates a side of the kettle which should be in shadow because of the position of the lantern.
Continuity mistake: Joe and his friend load four barrels into the buckboard, but when his friend arrives in town there are only two. When it arrives back at friend's cabin, there are four barrels again. (00:27:00 - 00:28:00)
