When Laura slams the door and breaks the picture window, it is the window in the front of the house by the door. When Charles is putting the old window back in at the end, the camera zooms out and the window is on the side of the house.
Laura broke the first plate glass window, then the old window with sash is back that night. Then at 33:51 the window is boarded up when Charles brought the second one home.
The bush Charles fell into with the third window glass was a poisonous white oleander. They are native to Africa and the Mediterranean, and do not grow in Minnesota.
At 29:00 during the fight between Laura Ingalls Wilder and Brenda Sue Longworth you see Brenda with an ink spot on her forehead for a split second, yet right before you see it, the inkwell is sitting upright on the ground with the lid on 2 feet away from her and Laura.
