Audio problem: Near the end, when Leech points his gun at Crusher, there is the sound of him cocking the weapon. However, when we see his gun immediately thereafter, the hammer is in the uncocked position.
Other mistake: As Crusher enters the police station, Data says "Hiya, Doc. What's cookin?" He's supposed to be incapable of using contractions.
Revealing mistake: As Data looks at the information on Dixon Hill, as the computer flash feeds, you can see that it's all the same block of information starting with the title of the first novel, which is the title of the episode, "The Big Goodbye."
Revealing mistake: When Picard looks out the window of the Dixon Hill office he sees the cars passing by each other, the traffic light is right in front of the window as if the entire building is not only in the middle of the street but only one story high.
Character mistake: When the away team transports down to the planet, Data is wearing three full rank pips denoting the rank of a full Commander, rather than his actual rank of Lieutenant Commander. (00:09:39)
Continuity mistake: After drinking some spiked Champagne from Lore, Data falls backward, yet lands on his face.
Other mistake: In this episode, when Riker makes his log entry, he says the stardate is "4124.5, " the 4-digit style of stardates from The Original Series, rather than the 5 digit style used in The Next Generation.
Continuity mistake: Near the end of the episode, right after Lore fires the phaser at Dr. Crusher, Data tackles Lore and knocks the phaser out of Lore's hand. The phaser flies towards the cargo transporter and when it impacts, it breaks in two. You can see a piece of it go flying off to the left. Then shortly after when Data throws Lore onto the transporter pad and Lore picks up the phaser, it's in one piece again.
Continuity mistake: When Lore backhands Worf in the turbolift, his eyes close but open back up as he is sinking down. Then, in the close-up, his eyes are closed again.
Continuity mistake: As Lore opens a channel, there's a blinking red light over the key he uses that disappears after the angle change.
Visible crew/equipment: When Will is wearing the (unforgettable) indigenous apparel for his meeting with Beata, the moving boom mic casts a shadow on the wall on the right side of the screen. (00:16:25)
Continuity mistake: When Wesley Crusher and his school chum accidentally hit Picard with a snowball from the holodeck doorway, it makes a huge wet spot on the captain's left shoulder. However, when Picard tells them "Don't let it happen again," as he turns to walk away, the wet spot is now suddenly dry. (00:36:00)
Visible crew/equipment: When Riker goes to meet Beata, they sit on the bed together drinking something. As Beata puts her glass down, a hand in the lower right-hand corner reaches for it and removes it for her.
Continuity mistake: Watch when Geordi on the bridge calls up Dr. Crusher in Sick Bay. There's a white-haired medical assistant working on someone behind Geordi. Then when Dr. Crusher responds to Geordi's page, the same assistant is down in Sick Bay with her. Then they cut back to Geordi and the assistant is back up on the bridge again.
Continuity mistake: When Beata tells Riker that he attracts her like no other man, her hand disappears from his neck.
Plot hole: The crew makes no attempt to re-board the Enterprise or stop it from leaving the starbase even after they find out there is no danger from the anti-matter.
Suggested correction: That characteristic was not added to the character until season two. In the first season, Data uses contractions on a number of occasions.
It's still a possible mistake, even if it wasn't part of season 1 scripting. Just because we only learn later that Data doesn't use contractions, doesn't make this mistake invalid. We learn Data was specifically constructed that way and hadn't been able to use contraction since being created, which means all of season 1 he shouldn't be using contractions. Although it would probably be best to submit it as a mistake in season 2 when it's mentioned that it contradicts what was established.

It would only be a mistake if he used the contraction after the trait was established for the character.
Possibly, but that's not how mistakes on this site work seem to work. It could still be a valid mistake in the context of the entire show since the character trait had in fact been established. It's the same way for when shows do something like establish a character's birth-date in later seasons, but when episodes from earlier season have the character at the wrong age. Although it would probably be best to submit it as a mistake in season 2 when it's mentioned that it contradicts what was established.
