Continuity mistake: When Tess is fixing the windmill, there is a strong wind blowing, as you can see on the turning windmill and on Tess' hair. When the three other girls look at the windmill from farther away, the windmill isn't turning at all.
Stir Crazy - S1-E8
Continuity mistake: When they are going after the horse they land with the chopper near the boundary fence. Watch behind Alex and Claire, the rotor isn't turning anymore. However when Tess and Becky arrive the rotor is still turning. This happenes more than once.
Dirty Pool - S1-E14
Continuity mistake: When Tess is stuck in the mud with her car and Alex is helping her to get out, during their "fight" the mud on Tess' blouse changes a lot.
Continuity mistake: When Tess is wetting her new boots, check the strand of hair that is hanging over her left shoulder. It changes between the shots looking direct at her and the shots of Meg and Jodie where you see Tess in the mirror.
