Visible crew/equipment: During the last scene in the infirmary, Bashir has a word with O'Brien about Garak's condition. Then, just as O'Brien walks towards Garak, on the console's reflective surface, we can see the reflection of the moving boom mic (beside the ceiling's black stripe pattern) at the bottom of the screen. (00:42:50)
Visible crew/equipment: After Kai Winn grasps Sisko's ear to feel his pagh, it soon cuts to Jake delivering half the items to Dr. Giger, and when Giger removes the chip that Jake brought on the cart, the actor's yellow tape mark is visible on the floor near Giger's consoles. (00:31:00)
Visible crew/equipment: After Garak takes out the first Cardassian while hiding in the broken stasis chamber, when it cuts to Nog walking towards O'Brien, there are three tape marks visible on the floor behind O'Brien. (00:25:25)
Visible crew/equipment: When everyone returns to DS9, Worf and Jadzia reunite and kiss. Then, in the next shot, just as O'Brien calls out to Quark, there's a visible T-mark on the floor. (00:42:15)
Continuity mistake: Since Dax's spots were stencilled on individually every day, the shapes and patterns have a tendency to change slightly from scene to scene in any given episode.
Suggested correction: Unless you can cite a specific instance where the change is obvious (taking stills and minutely comparing the patterns doesn't count), this is much too vague to count as a mistake.
Character mistake: Sisko states they are attempting to create the first artificial wormhole (as in constructed). The problem is, the pilot episode over three years earlier established that the Bajoran wormhole wasn't natural, but constructed by the Prophets.
Revealing mistake: Lt. Commander Eddington is wearing the rank insignia of a junior grade lieutenant.
Trials and Tribble-ations - S5-E6
Continuity mistake: When Dr. Bashir picks up the chair in the bar, he grabs it by the armrests. But in the next shot, he's holding it by the back.
What You Leave Behind (1) - S7-E25
Visible crew/equipment: In the scene with Ezri and Bashir in bed together, Ezri appears to be nude. However, when the camera pans over them, you can see tape over her chest and her spots abruptly end. (00:00:35)
Continuity mistake: At the beginning of the episode when arriving at the station, Worf's brother has normal human bottom teeth. Later in the episode, he is wearing Klingon bottom teeth cosmetics.
Continuity mistake: When the runabout is shot by the Dominion ship, Jake is sitting in the left seat, but when he is thrown off his chair by an explosion, he is on the right seat. (00:09:10)
Continuity mistake: When Jadzia tells Benjamin she is going to do helioscismic measurements of the sun, the camera shifts in mid-sentence. In the first shot she is rubbing her hands in front of her, in the second shot, her hands are clasped behind her back. (00:15:20)
Other mistake: When the Klingon, Kozak, falls on his knife during his fight with Quark his blood is a deep red. It should be pink like any other Klingon. (00:02:20)
Suggested correction: Klingon blood is only shown as pink in the film Star Trek VI: The Undiscovered Country and in the series Star Trek: Discovery. In the case of the former, the blood was shown as pink/lavender to have it appear alien and also to avoid rating issues (that much blood would have given the film an R rating). This is an inconsistency in the entire Star Trek universe at large, or perhaps only in those two stated instances, and not a mistake in this particular episode as the number of times Klingon blood has been red greatly outweighs the few times it has been shown as pink.
Continuity mistake: When Bashir goes to let Garak out of the crawlspace, he pulls the prying tool from under the end of the bunk mattress closest to him. But in the scene before a Romulan prisoner had put it under the opposite end of the mattress.
Continuity mistake: The episode includes Odo as one of the people who is still alive after "200 years." However, in later seasons, it is revealed that Odo was infected with the morphogenetic virus by Section 31 quite a while ago. And given that in those later seasons, he is deteriorating and dying, there is no possible way that the "Future Odo" from this episode could've survived 200 years since he likely wouldn't have survived more than a decade since this episode if they became trapped back in time.
A Man Alone - S1-E4
Other mistake: The word "Shifter" is written in English on Odo's office wall. Obviously, this is done for the benefit of the audience, but on a Bajoran space station near their home planet the word should have been written in their native language.
Trials and Tribble-ations - S5-E6
Other mistake: The doors of the old Enterprise in this episode open and close much slower than the original series, thereby causing the original sound effect to have to be extended.
Trials and Tribble-ations - S5-E6
Continuity mistake: On the old Enterprise bridge, Sisko is shown at a bridge station, and the person next to him, close to Dax's position, is wearing a gold shirt. When Kirk comes onto the bridge, the person next to Dax now has a red shirt, which was the original crewman's shirt in TOS.
