The Night of the Eccentrics - S2-E1
Visible crew/equipment: West walks through the gate into the amusement park and twice passes very visible truck tire treadmarks in the dirt street. (00:09:30)
The Night of the Eccentrics - S2-E1
Revealing mistake: Tony throws two knives at West - but on the wall where the knives hit, the rectangular openings from which the blades actually emerge are delineated beforehand. Happens again a few scenes later, where slots cut in the door are already there before the knives are thrown. [Spoiler: It's inconsequential to the "revealing" error, but if you play the scene in slow motion, you can see that both times, the knives pop through from the back of the "wall." This is also how the carnival trick is performed.] (00:17:05)
The Night of the Eccentrics - S2-E1
Visible crew/equipment: When the Eccentrics outline their nefarious plan to assassinate Juarez, the boom mike shadow is moving on the door behind West and Gordon. (00:28:30)
The Night of the Eccentrics - S2-E1
Visible crew/equipment: Behind West, when he's suspended over the electrical field, you can see the shadow of the boom mike and rigging pole moving on the wall. (00:35:05)
The Night of the Eccentrics - S2-E1
Revealing mistake: Two scenes after the opening credits, West fights the strongman Titan. When Titan throws West (who is horizontally positioned on Titan's shoulders) down to the ground through the circus tent, a mattress upon which West lands is mistakenly exposed.
The Night of the Eccentrics - S2-E1
Revealing mistake: The eyes of Vance Markham's corpse move before he falls over.
The Night of the Golden Cobra - S2-E2
Continuity mistake: At the beginning of the closing scene, their private train is shown moving right next to tall green trees with large mountains directly behind the trees. The final shot of the scene shows the train in a very desert-like location moving towards the trees and mountains which are shown in the far distance.
The Night of the Golden Cobra - S2-E2
Visible crew/equipment: The shadow of a camera is seen on the couch as Artemus gets up from the couch.
The Night of the Golden Cobra - S2-E2
Revealing mistake: Indentations from West striking the board with his knuckles are seen before he hits it with his fist.
The Night of the Raven - S2-E3
Continuity mistake: Because the second one is a painted backdrop, the building across the street from the sheriff's office in the exterior shots looks nothing like the one we can see from inside the office in the next scene. (00:07:00)
The Night of the Raven - S2-E3
Continuity mistake: West and Gordon are ordered to sit on the floor to talk to the diminutive Dr. Loveless at eye level. In all the two-shots, their shoulders are touching. In all the wider angles, they're sitting a foot apart. (00:09:05)
The Night of the Raven - S2-E3
Continuity mistake: Dr. Loveless' henchmen remove Artemus' leg chain. But a few scenes later, he's shown asleep in a chair, and the chain is back around his ankle. (00:28:35)
The Night of the Raven - S2-E3
Continuity mistake: In the reverse angle shot of West's table, the plates, candles and red table cloth are all there - but the huge dish of butter has disappeared. (00:39:20)

Other mistake: Balya, the Turkish representative, is killed by a knife protruding through the back of his chair. But when he falls to the floor, leaving the knife behind, there's no blood on the blade. (00:42:00)
The Night of the Raven - S2-E3
Continuity mistake: West stabs the giant cat in the left front paw. But when the cat is shown licking its wound, the injury is on its right front foot instead. (00:46:15)
The Night of the Raven - S2-E3
Revealing mistake: When the marshal opens the train's rear door and comes in to arrest Lana, you can see wrinkles in the "sky" outside. It's really a painted cloth backdrop. (00:48:40)
The Night of the Raven - S2-E3
Continuity mistake: Three fourths into this episode, West is inside the wall of the mouse hole. Wearing his blue suit, he enters a knot in the wall onto a ramp. While sliding down, West is now wearing an emerald green suit. When West is sliding into the octagon container, he is wearing the blue suit again.
The Night of the Raven - S2-E3
Continuity mistake: West enters through a bedroom window that, from the outside, is dark inside, but when he climbs in, the room is now brightly lit.
