Continuity mistake: When Deckard awakens in Wallace's office, after Wallace's visual aids leave and Deckard hears Wallace, he is lying back in the seat with his arms in the armrests. The shot cuts to an angle behind Deckard, where he is now suddenly hunched forwards. (02:09:15)
Continuity mistake: When Wallace says to Deckard "It was very clever to keep yourself empty of information, and all it cost you was everything. But you can still help me", the light above them begins to shine on Deckard, and his shoulder is covered in light. The shot cuts to a shot in front of Deckard, where his shoulder is suddenly much more shadowed, before being lit a second time. (02:13:20)
Continuity mistake: When the giant Joi walks over to K, the wide shot shows her stopping in front of the platform he is standing on, directly facing K's direction. The shot cuts to her kneeling down, and she has suddenly turned 90° to the left. (02:17:00)
Continuity mistake: In Sapper Morton's garden, when K finds the small plant next to the tree, he sniffs the plant and lowers his hand slightly, with his hand and the plant pointing upwards. The shot then cuts to an angle further away, where his hand and the plant are suddenly pointing to the side. (00:11:50)
Continuity mistake: When K is at his apartment, Joi lights his cigarette which smokes slightly. The shot cuts to a different angle, and there's much more smoke. (00:18:20)
Continuity mistake: When K is smoking a cigarette in his apartment, he blows the smoke towards Joi which passes through her. K then lowers the cigarette to his lap, and some additional smoke can be seen emerging from the cigarette at the bottom of the shot. The shot cuts to K beginning to move his legs, and the additional smoke has vanished. (00:18:25)
Continuity mistake: When K and Joi are talking at the apartment after K returns home, Joi picks up the Pale Fire book and K tells her she hates that book. Behind K's head is some smoke from the cigarette he smoked when he is saying the line. Joi then says she doesn't want to read either, and the smoke behind K's head has disappeared. (00:18:45)
Continuity mistake: When the LAPD are looking over the bones, there is a shot of the teeth from the skeleton being placed on a table one at a time. The shot cuts to another angle of the table to focus on the hair sample, and the part of the table where the teeth have been placed is still visible in shot, but the teeth are suddenly nowhere in sight. (00:24:05)
Continuity mistake: When Coco is examining the skeleton, the shots of Coco in focus show Lieutenant Joshi in the background leaning her elbow on the medical table, and remains this way until Coco says "Sorry" after referring to Sapper Morton as a sentimental skin job. Joshi then asks where's the kid and she suddenly has her arms crossed and not leaning on the table. This isn't very easy to see when she is asking, but is noticeable when Coco gets up from his seat in the next shot. (00:25:35)
Continuity mistake: After examining the skeleton, Coco gets up from his seat and K starts to walk towards the console to examine the skeleton himself. When K begins to walk over to the console, Joshi has her arms by her side, but in the next shot, her arms are suddenly crossed. (00:25:50)
Continuity mistake: When K is getting out of his car after the scavengers break the door open, he struggles to stand, holding onto the side of the car. One of the scavengers then runs up to K, next to the car. K then fights back and he is suddenly standing upright, several meters away from the car. (01:02:45)
Continuity mistake: When K is ambushed by the scavengers, the first one attacks him and K breaks his back with his knee. A second one then attacks him and K drops the first. When the first is dropped, the body is positioned near the car. Seconds later, when K is blasted back by an explosion, the first scavenger that attacked K has moved more ahead of the car. Also, when Luv is shown watching K from her perspective, the first scavenger's body has now moved again, several meters away from the car. (01:02:50 - 01:03:50)
Continuity mistake: When K fires at the scavengers in the scrap yard, he keeps his gun pointed at them and an additional group of scavengers runs over a hill in the background. The shot cuts to an angle behind K, with his arm lowered, but in the next shot, his arm is suddenly raised and aiming again. (01:03:00)
Continuity mistake: When K is visiting Dr. Stelline in her facility, he has a bloody bruise next to his eye and eyebrow. This remains on his face for most of the scene, but when Stelline tells K that we recall memories with our feelings, the bruise has disappeared. (01:19:40)
Continuity mistake: Dr. Stelline offers to analyse K's memory to see if it is real. She sits down on a bench where her console is shown and is smiling with her mouth closed. K then sits down on a bench on his side of the glass. When this happens, Dr. Stelline's reflection can be seen in the glass, and she is now smiling with her mouth open. (01:20:15)
Continuity mistake: When K arrives at Dr. Stelline's facility with Deckard, his left ear is visibly mangled and injured. At no other point in the movie or in any prior scene, did his ear have this damage done to it. It just appears in this scene out of nowhere. (02:29:10)
Continuity mistake: When K frees Deckard from his restraints after drowning Luv, K pulls Deckard out of the water with his right hand, grabbing onto Deckard's shoulder. In the next shot, K suddenly has his right hand on the ceiling of the car. (02:25:45)
Continuity mistake: When K gives Deckard the wooden horse, he tells him "all the best memories are hers" whilst looking at him, but in the next shot, K is suddenly looking at the wooden horse. (02:29:00)
Continuity mistake: In the sinking car, when K frees Deckard from his restraints, he pulls Deckard so he is above the water. Deckard has his left hand above the water when he is pulled out, but in the next shot, his hand is suddenly below the water. (02:25:45)
Continuity mistake: When K hands the hair sample to the clerk at Wallace Corporation, the clerk puts down the note with the serial number for the replicant, and places it on the desk, with part of it positioned in front of the keyboard. From another angle, the note cannot be seen. This could not be due to the clerk's head blocking it, because the note was placed in front of the keyboard, and the keyboard is fully visible in shot with no note visible in front of it. (00:29:45)
Answer: The birth records were purposefully mixed to hide Ana Stelline (Rachael and Deckard's daughter). She was passed off as a boy and raised in the orphanage. K was given her memories because she secretly was giving replicants pleasant memories of her own. She is in a containment area because it is said she has an autoimmune disorder, but this is likely a ploy by the freedom fighters to keep anyone from examining her and discovering that she is at least part replicant.
