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.

(00:32:40)
The Night of the Tottering Tontine - S2-E16

The Night of the Bottomless Pit - S2-E8
Continuity mistake: When they attack him, Artemus' cellmates are smacked with a wooden chair, which lands broken but upright on the floor. In the very next shot, though, as Artie throws the exploding cigar, the chair is suddenly lying on its side. (00:25:30)

The Night of the Man-Eating House - S2-E12
Continuity mistake: West and Gordon drag Day from the haunted house, prop him on the porch and turn away. When they turn back, they're stunned to see that he's aged 30 years. But if you look closely, you can see that the man they prop on the porch is already gray-bearded and shaggy. So why were they surprised? (00:44:30)
