The Conflict - S3-E1
Other mistake: While Martha Corinne is standing in front of the bathroom sink in the new house, we see her height compared to the mirrored medicine cabinet above the sink, and Martha Corinne is quite a bit shorter than the mirror's knob, even with her bonnet. When she reaches up to open the cabinet door, in the next closeup from behind her she is now taller than that knob. For this specific closeup The Actress was presumably standing on a stool, in order to have the perfect shot of her turning her head, then being surprised by her own reflection in the mirror.

The Conflict - S3-E1
Other mistake: After seeing the new house, Martha Corinne and Esther are at the back of the truck talking while John is driving home. During their conversation the truck is not actually moving (it's shaken to give an impression of movement), as we can see no change in scenery through the small rear window and at the left side of the screen in shots facing Esther. Additionally, Olivia is visible through the rear window sitting in the front seat, and she's wearing dangle earrings, which she does not wear in the scenes before or after (presumably it's the stand-in sitting in the seat). (01:01:10)
The Spoilers - S3-E8
Other mistake: During the somewhat pointed discussion with the Hanover family at dinner, Olivia suddenly has the girls help clear the table when all their plates are still full, which wouldn't happen during a depression with money so tight.
