Relativity - S3-E10
Visible crew/equipment: When Stark and Aeryn are back aboard Talyn with Xhalax, who is tied up, when Stark says, "As far as I can tell, Talyn's systems are almost back to normal," we can see the puppeteer's face (wearing a weird black mask) and hands under Rygel's hoverchair.

Other mistake: While in the past on the Jocacean Memorial Planet, Sub-Officer Dacon is sent up on the wall by his commander. Then, when the Venek Horde are coming over the wall Aeryn pulls one down and throws him to the ground, and we can see an armor piece lying on the ground, with the name "Dacon" written on the inside of the prop in English.
Visible crew/equipment: After Chiana and Jothee lie to Rygel about a pot that exploded which caused the mess, it cuts to the room where Scorpius and his men are holed up while looking at a hologram map of the clinic, and in the first shot facing Grunchlk and Kobrin the boom mic dips into view at the top of the screen.

Trivia: While they're waiting for the Venek Horde to attack again, when John is chained to the statue, Harvey/Scorpius is playing the harmonica with his feet up on John's lap. Notice that both soles of Harvey's red boots have the name "Andy" written on them. In "Toy Story" Woody's boot has "Andy" written on its sole, and here in John's mind it's to signify John's ownership of the neural clone.
Continuity mistake: After Aeryn uses up D'Argo's Qualta blade on the Scarran who's after John and D'Argo, John grabs a huge icicle and plunges it into Plonek's chest with his right hand, but in the close-up John's using his left hand, then in the next shot the icicle's back in his right hand.
Visible crew/equipment: When Stark and Sierjna go to Talyn's rudimentary pilot's den, notice that Stark's vest has suddenly developed five randomly placed grommet openings, which will be where Talyn's wiring will attach when Talyn bonds with Stark. And when Stark-Pilot says, "Talyn you will turn away, you must turn away," there's boom movement at the right and left of the screen. Also, later when Stark-Pilot flies Talyn closer to the sun to rescue Sierjna, and once she reappears, there's a shot from behind Stark-Pilot and we can see the long rod (not Talyn's wiring) that's behind his right leg attached to his pants, which is part of the support equipment to have Stark-Pilot hover.
Chosen answer: It's never explained. John mentions a theory that his less technologically developed craft simply interferes with the wormhole less than the "superior" Vipers, but they never make a concrete determination on that point. But we also have to take into account the fact that Moya traverses wormholes with no ill effect as well.
