Spoilers can be discussed now as it's been two months since Afterlife came out.
I'd not noticed that one, but costume errors do happen, sometimes on small levels, sometimes on big ones (one I recall from
Ghostbusters was the black square was missing from the inside of the elbow pad in some scenes, one from
Ghostbusters II is that when Winston breaks down the door to save Egon and Ray from the Vigo-started fire, his uniform is missing the logo patch from the arm.
Another continuity error I spotted is when Wrecto-1 is driving to the mine/temple to confront Gozer, there's a moment when the emergency lights are seen inactive, but the shots bookending this shot did have the lights going.
What likely happened is the production used some footage from the Muncher chase and inserted it into a later moment in the film. There are a couple of other moments where Wrecto's lights are off when it's arrived at Egon's farm... But we've been having continuity issues with the car's lights going back to the first two movies.
