Once on a Day in Spring - S2-E20
Continuity mistake: During Victoria's conversation with Vaquero in the tent, the red blanket wrapped around her changes positions (up near her ears, then falling off her shoulders, etc.) several times between takes.
Continuity mistake: Two of the ten orphaned Apache children are found hiding near the house, bringing the total so far to six. But later, after Chodi sends out a signal, two more children come in from the desert, and these are again counted as five and six. But the fifth and sixth of the children were already there - so the new total should have been eight, not six.
The Stallion - S2-E1
Continuity mistake: Blue leaves his regular horse exhausted at the ranch and takes another one in order to pursue the young Apache. But in mid-chase, Blue is suddenly back on his regular horse again.
Continuity mistake: Victoria is wearing a torn white blouse after the stage coach overturns, then, after she and Jim are walking through the desert, and they find water, she is wearing a pristine pink blouse. Then, a later shot shows the white blouse again, and while she and Jim are camping for the night, she is shown changing into the pink blouse.
