The Night of the Wolf - S2-E27
Revealing mistake: Though the stock footage is of a real wolf, the animal West wrestles with is too-obviously a dog wearing a fake pair of wolf ears. In later wrestling matches between West and the wolves, the attacking beast is a stuffed prop that never moves its legs, head or jaws at all. (00:03:30)

Visible crew/equipment: When the stagecoach pulls into the station, tracks from the camera truck can be seen in the dirt. (00:06:00)
The Night of the Wolf - S2-E27
Continuity mistake: West's coat collar alternates from turned up to turned down several times as the shots change. This continues to occur throughout the episode. (00:17:30)

Revealing mistake: Talamantes' giant pet spider looks pretty impressive - until it moves and reveals that its wiggling legs are made of rubber. (00:23:30)
The Night of the Wolf - S2-E27
Continuity mistake: The boot heel West removes to obtain his hidden explosive somehow reattaches itself by the time he leaps into the mining car. (He doesn't stop to put it back - he's running for his life from a pack of hungry wolves.) His boots also change from black to brown by the time he makes it outside and jumps on his trusty horse.

Factual error: Several airplane contrails are visible in the sky as West gallops his horse to Stefan's coronation.
