Journey In The Spring (1) - S3-E6
Revealing mistake: When Charles notices that his dad set the house on fire, and he is at his mom's wooden grave site, the wooden grave marker moves when he gets up to save his Pa from the burning house.
The Rivals - S4-E14
Continuity mistake: Laura almost bumps into the boy after they get out of the lake and she looks as if she wants to kiss him. In his point of view, he is standing further away from her. In the next shot she is a few inches away from him.
There's No Place Like Home (2) - S5-E6
Continuity mistake: At the end, when Lars Hanson hears the church bell ringing, he gets up from his bed and goes to look out the window. When he first gets up, his hair is completely tousled - definite "bed head." The shot changes to show him leaning out the window, and his hair is neatly combed. When the shot returns to the inside of the room, his hair is once again rumpled and untidy.
Continuity mistake: Grace Snider Edwards was played by two different people with no explanation. Bonnie Bartlett played her all along, but Corinne Camacho played her for one episode only.
Character mistake: When Eric is asked to spell repetitious at the spelling bee he spells it R E P I T I T I O U S... Alice Garvey says "correct" but it was incorrectly spelled.
Deliberate mistake: When Mary gets to the school where she is going to be teaching, all the children are standing outside wearing shoes. However when they come in to the school they are barefoot. I have a feeling this was done to show how poor the community she was teaching in was supposed to be, but it looked like too cold and rainy of a day to let the actors be outside barefoot.
Continuity mistake: When Edwards is first discovered missing by Grace, the moon is in the background in the center of the screen. After all the time that goes by with Edwards in the casino, Charles looking for him, finds him and goes all the way back to where they were sleeping (figure at least an hour or more), the moon is still in the exact same position in center of screen from the exact same camera angle. In reality, the moon would have been more to the right or disappeared completely by now (depending on the timespan).
Someone Please Love Me - S5-E22
Continuity mistake: Charles walks down the staircase with a small trunk, suitcase, and a duffel bag. He finishes business from the man he bought the horses. When he walks out onto the porch, Charles is only carrying his duffel bag, and tosses it into his wagon. No other luggage is visible.
Times Are Changing (2) - S9-E2
Factual error: This episode takes place around 1886/1887 and in the episode Royal dies. In real life, Royal didn't die until 1925.
Visible crew/equipment: When Michael Landon is chasing the boy at the carnival, the shadows of the crew can be seen on the bottom of the frame as he is running.
As Long As We're Together (2) - S5-E2
Revealing mistake: When Charles Ingalls plays his fiddle at the end of the episode, one can see from the movement of his hands that he is not really playing, but just pretending. (Also visible in every other episode where Charles plays the fiddle, but most obvious in this one.).
The Nephews - S7-E14
Factual error: Royal Wilder promises to give his sons an Indian Head nickel if they are well behaved at Almanzo's/Laura's house. The Indian Head nickel was not minted until 1913 - 30 to 40 years later.
Factual error: Right as Michael Landon boards the train off his horse you can see a radio tower in the background. Radio hadn't been invented when the show was set.
The Campout - S2-E5
Audio problem: When Laura and Nellie are on the branch going down the rapids they can be heard talking, but their mouths either don't match with what they are saying or don't move at all.
The Raccoon - S1-E10
Plot hole: The plot gets confusing here. First, Laura and Jack (the dog) are rabidly bitten by Jasper (her pet racoon). The doctor warns they may have rabies from the bite. A second more dangerous raccoon is discovered which eventually left the area. In the end, Charles (discovering there were two raccoons in the barn after finding Jasper remaining), says Laura is going to be OK after all. The main confusion is that Laura would still be in danger from the bite regardless of which untested raccoon bit her.
Continuity mistake: When Laura pushes Mrs. Pierce, she lands in a pail of water on her buttocks, and her hair remains dry. The next shot is of Laura saying something, then in the very next shot we see Mrs. Pierce still sitting in the bucket, only now her hair is soaked. Since she landed on her behind, her hair should not have been soaked, and there was no time for anyone to pour water on her head between the shots.
Revealing mistake: When Carrie (played by twins) falls down in the opening sequence, it appears that she gets back up and continues running. In reality, after falling, the other twin gets up and continues. If you look closely enough, you can see that when getting up, Carrie is slightly closer towards the camera than when the first twin fell.
Factual error: A modern day fire extinguisher is shown on a beam Charles walks next to in the town of Bixby.
Factual error: When the older boys are lying around the playground discussing The Election, you can see the bottom of the boy's shoe. It is made of molded rubber and features a "tread" on the bottom. This would not be how shoes were made in that time period.
The Campout - S2-E5
Factual error: This episode takes place almost entirely in the mountains. In Minnesota where the show is set, there are no mountains as tall as shown, particularly those that are snow-capped and rocky. The show was shot in California.
