Continuity mistake: When Seven and Naomi are playing Kadis-Kot, the pieces on the board and on the table change after Seven wins in the next shot.
Other mistake: When Neelix and the Captain are following the unknown creature, it turns down a hallway and Neelix says it just ran into a dead end. The two follow and enter the transporter room on their right. However, when they exit the room, they turn to their right again, which should lead to a dead end. They needed to go to their left to go back to where they came from.
Continuity mistake: The sun's location changes when Rain and Tom are in the stalled van. After Tom shoots the truck and Rain stops the van, you see the shadow is directly under the van. When the truck is heading towards them, we see the van's long shadow across the highway, to the right of the van.
Continuity mistake: When Samantha is holding her baby while the captain talks to her, her hands are apart with her right hand under the baby. In the next shot, her right hand is on top of her left hand and not under the baby.
Continuity mistake: In sickbay, when Kim tells the captain he's analyzed the tricorder, the tricorder is open. In the next shot it's closed.
Continuity mistake: Tuvok announces to the bridge he has detected a "polaron grid" surrounding the planet Voyager is orbiting. Minutes later, Chakotay tells the Captain that they have found some small holes in the "tachyon grid". (00:25:50 - 00:29:30)
Character mistake: Species 8472 was trapped on deck 11, behind a force field. When the ship comes under attack by Hirogen, Seven is instructed to get down to deck 11 with a supply of nanoprobes. In the meantime the Hirogen hunter escapes from Sickbay (deck 5) and soon faces off Seven and attacks 8472. When Seven beams them off the ship, Harry says that 'someone has tapped into transporter control on deck 5'. (00:39:00)
The Haunting of Deck Twelve - S6-E25
Character mistake: When Chakotay states they have collected 80% of deuterium and he suggests to stop taking in more, Captain Janeway agrees and she then tells B'Lana that they will stop taking in dilithium. (00:09:50)
Character mistake: As Voyager is bombarded by the cyclone, Paris reports that Voyager is at 20,000 meters and falling. 28 seconds later, he reports that Voyager is at 18,000 meters and states that, at this rate, they will crash in 10 minutes. However, if they drop 2000 meters in 28 seconds, they would actually crash in 252 seconds (just over 4 minutes). One might argue that perhaps it was calculated that their descent would slow down as they approached the surface, but later they fall from 2000 meters to 1000 meters in 14 seconds - the same rate.
Revealing mistake: When Kes is eating the spawn beetles, the same shot is used twice for when she scoops out beetles from the tray. The untouched beetles are all in the same place, and there is a beetle that is nearly flipped by her thumb both times.
Projections - S2-E3
Other mistake: At the beginning of the episode, as B'Elanna is working her way out through the doors, the Doctor cowers and tries to hide behind things. There is no reason for him to be afraid. He can't be hurt under normal conditions - this proves to be the case later when he feels pain and says he is not programmed to feel pain, and we learned earlier in "Phage" that he can change whether or not things pass through him.
Continuity mistake: In the scene where Tuvok is performing the meld Seven of Nine's hair is noticeably out of place as a result of struggling in the restraints, yet just after the Vinculum is deactivated it is neatly back in place. (00:38:15 - 00:42:50)
Continuity mistake: Through the series, it is stated several times that Voyager has three transporter rooms, like in Phage (season 1 episode 5). However, in this episode, Voyager suddenly only has two transporter rooms.
Continuity mistake: In episode Revulsion (Season 4 episode 5), commander Chakotay says that Voyager's astrometrics laboratory hasn't been updated since the ship left space-docks. In later episodes it is stated that Voyager didn't have an astrometrics when it was built. In Shattered (season 7 episode 11), Chakotay time-travels back to the day Voyager leaves for its first mission and tells that times Janeway that they are going to the astrometrics, to which Janeway comments, "Voyager doesn't have an astrometrics".
The Voyager Conspiracy - S6-E9
Factual error: When the alien contacts Voyager after his catapult jump, he states that he is 5,000 light years away. Despite the distance, he and Janeway have a real time conversation. With this incredible communications technology, Voyager (which is at this point less than 55,000 light years from the Alpha Quadrant) should be able to have several back and forth conversations a day with Starfleet.
Character mistake: Captain Janeway's main goal in this episode is to proceed to the holodeck and shut down the lightning shield protecting Chaotica's death ray so Lt. Paris can shoot it with his destructo beam. Throughout the scene where Lt. Paris further briefs Capt. Janeway on her way to the holodeck, the plot is such that her goal is to shut down the death ray, not the lightning shield. (00:26:20)
Suggested correction: They are trying to shut down everything in the Holodeck simulation.
Character mistake: B'Elanna replicates and assembles a television from 1956, including a remote control. Tom however says they didn't have remote controls in the 50's. The first wireless remote was invented in 1955 and the "Zenith Space Command" (a remote looking similar to the one in use) came out in 1956, which fits the timeline. Tom is vastly aware of 1950's technology (he seems to know when the television remote came out) and wouldn't make that mistake or B'Elanna would have corrected him given how much research she had to do to set the whole thing up.
Continuity mistake: As Janeway calls the bridge after a conduit is blown out by Kes, her combadge is askew. A moment later when they meet Tuvok, it's correct.
