Audio problem: Anthony Hopkins is in his car with Cogman, discussing Pangea the super continent over the phone with John Turturro. There are two instances in this scene in which Anthony Hopkins' voice has been dubbed over by a different actor that does not sound like him. Anthony Hopkins first says "That's Pangea. The super continent." The scene then flashes back to the round table and the dubbed voice attempting to sound like Hopkins says "It's the same shape on the round table." The dubbed voice is heard again when he says "Genius", before reverting back to Anthony Hopkins immediately after when he says "Stonehenge."
Audio problem: Just after K finds the 6 10 21 marking on Sapper Morton's tree, he begins to head back to his car. In the shot from behind K where he is first walking to the car, the only sounds heard in the shot are his footsteps and nothing else. The shot then cuts to an angle behind the car with the door opening, and it is now shown that K has set Sapper's house on fire, and the sound effects of the flames burning are suddenly heard. The sound of the flames burning the house should have still been heard in the shot where K was walking up to his car as the house was already on fire. (00:49:15)

However it is just the added sound effect as there is not one single fly or insect visible. (00:09:35)
