Other mistake: A crowd of men is awaiting the arrival of saloon singer Dolly Bantree. When the stage pulls up, she exits carrying a small bag. Hoss offers to carry her luggage and then is dismayed when the stage pulls away and he sees 20 more bags stacked in the street. The 20 bags were not atop the stage, nor would there have been room for them inside the stage.
Plot hole: Laurie Ferguson is outside the Ponderosa ranch with Joe Cartwright. In an attempt to frame him for sexually assaulting her, she begins screaming. She emits six loud piercing screams before the scene shifts to Ben, Hoss and her father and brother inside the home. It is not until her seventh scream that the four men look up and start to run outside.
