The Night That Terror Stalked the Town - S1-E10
Continuity mistake: Three fourths into this episode, West is in a room with an hourglass. The hourglass shows a few grains of sand before it empties.

The Night of Sudden Death - S1-E4
Continuity mistake: In the scene after the first freeze frame, Corinne is affixed on a round arrow target. Corinne's body keeps changing positions even though the target has stopped spinning.

Following long shot, she is horizontal (head at #3). This keeps occurring throughout this scene.
The Night of the Deadly Bed - S1-E2
