Other mistake: When they raise the temperature of the room with the facehuggers in, once the room is at body temperature, they open the door onto the much colder corridor. This would have immediately dropped the temp in the facehuggers' room.

1 other mistake - chronological order
Directed by: Fede Alvarez
Starring: Archie Renaux, Cailee Spaeny, Isabela Merced
Continuity mistake: After Rain shoots all the xenomorphs in zero gravity, and she and Andy have to traverse through the floating blood splatter, the bodies of the dead xenomorphs have suddenly disappeared.
Trivia: While Rain is eating and talking with Andy in the background, a dipping bird can be seen, just like in Alien and Alien: Covenant.
