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.

By Inferno's Light - S5-E15

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.

Grumpy Scot

A Simple Investigation - S5-E17

Continuity mistake: When Arissa is first interviewed in Odo's office, she displays a 'data port' that is embedded below and behind her left ear in her upper neck. Her hair is styled to make it visible, and the port seems to be there for the entire scene, tho almost completely obscured at times. The second time she's in Odo's office, her hair style is the same, making it very obvious the port has now vanished, and it's gone the entire scene. For the third visit to Odo's office, the port appears and disappears at random. Apparently this scene was comprised of shots from the two separate shoots that made up the first two office scenes.

Children of Time - S5-E22

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.
