For Better or Worse (2) - S3-E29
Other mistake: Cloud Dancing gives Sully his white Cheyenne tribal dress to wear as a wedding suit, but Sully pulls on a very different deerskin coat inside the barbershop.
Wave Goodbye - S6-E5
Plot hole: Dr. Mike and Daniel are discussing whether Princess Nizamoff is a fake or not, considering all the voices from the dead she performed during the séance. Yet Mike totally forgets that Mizamoff addressed her former medical professor in grave detail. Something the Princess would not have known otherwise.
Factual error: Near the end, when Horace is delivering Lincoln's Declaration speech, Mike and Sully are talking, you can see their breath. Indicating this was shot during the winter, when it's supposed to be July 4th Independence Day.
Other mistake: Toward the end, when Mike is snuggling at the window with Sully, the candle on the wall near them isn't lit. But there is ominous light about them, obviously from the studio set.
Character mistake: Loren mistakenly calls each pitch at the batter's mound a strike, when that is when a pitch is out of batting mounds, or the batter misses. A ball is when the batter ignores the pitch or doesn't make a swing.
Suggested correction: A player doesn't have to swing for a pitch to be a strike. He called them correctly.
Well unless I've missed something over the years in baseball... and Loren's obvious confusion on what to call... when a batter remains stationary during a pitch, that is a standard all-out ball. When the batter moves or swings and misses the pitch, it is a strike.
His initial hesitation had nothing to do with it being a bad call. And yes, you've missed a lot over the years. A batter can move or even check swing and still the pitch could be called a ball. When a batter remains stationary, that doesn't change a strike into a ball just because he didn't swing or attempt to swing. The poem "Casey at the Bat" is all about him not swinging on the first two pitches, and they were both called strikes.
The Tempest - S5-E10
Other mistake: Smoke from the burning Thanksgiving dinner starts wafting from the stove just moments before a strong wind from a coming storm blasts through the window. Yet somehow Michaela doesn't notice the smell just moments before going outside with Katie.
Other mistake: When Sully's wrist gets scraped while moving the examining bed off the wagon, Dr. Mike merely dabs over it with some disinfectant, instead of thoroughly cleansing the wound with a wet cloth before suturing like a normal doctor.
Revealing mistake: Obvious lip liner on Michaela in the end scene.
Dr. Quinn, Medicine Woman - S1-E1
Other mistake: When Emily is in crisis labor Dr. Mike sedates her and does a C section delivery. But Emily periodically regains consciousness during and after. Never once reacting to any pain from the cutting, which seems unlikely.
When a Child is Born (2) - S4-E28
Other mistake: Not to sound rude, but Jane (Seymour) was literally pregnant, in labor when her water broke, but no visible staining on her gown or on the wagon seat when Sully pulls her up.
Factual error: In the later seasons (4-6) all the characters keep referring to their location as 'Colorado Springs' instead of just stating 'here'. Example: "I told him to stay in Colorado Springs" instead of just stating "I told him to stay HERE"
