Continuity mistake: When Vicky gets carried away from the bedroom by the group of children, the sandal on her left foot falls off as she struggles. Later, in the cornfields, as she gets raised onto the large crucifix, the sandal is back on her foot. (00:53:25 - 00:57:00)

Continuity mistake: When Burt and Vicky are driving around and end up at the gas station, the sun is near sunset. But a few scenes later on, the sun is high like it's late morning, even though it takes place later on in the same day. (00:27:00)
Audio problem: When Sarah's mother is on the phone with her husband, she says, "I'm worried Dave, the fever's gone from 101 to 104," yet her mouth doesn't move. (00:02:30)

Continuity mistake: When we see the beginning of rebellion inside Hansen's Cafe, you can notice through the front window a building across the street with a sign saying something like "Stone Master Products". Three years later, when Burt and Vicky stop by Hansen's Cafe, the buildings that we saw before are nowhere to be seen - no rebuilding has occurred as the town is deserted except for the children. It is because the interior shots of the cafe were filmed in a different town.
Revealing mistake: When Vicky throws the lamp at the children, there's no power cord attached to it.
Revealing mistake: When Burt hits one of the children, the skid marks are in front of the car, when they should be behind it.
Continuity mistake: When Amos is saying "I'm ready to celebrate my birthday", priestess is looking at him. After that, Isaac starts yelling and when the shot changes, she is suddenly looking towards Isaac.
Chosen answer: Who knows? Maybe they blackmailed her, because she works there, and the children wouldn't get caught poisoning the coffee, or maybe she isn't as old as you think, she could well be in her mid 20's, it's hard to tell, you only see her briefly.
