Corrected entry: In the scene where Flagg is freeing Lloyd from prison, Randall Flagg extends his right hand, palm up, to Lloyd in a wide shot. Cut to closeup of Flagg's left hand (not right) holding a key that turns to a black stone. Cut back to 2-shot of Flagg and Lloyd with Flagg's right hand once again extended. Lloyd attempts to take the stone from Flagg's right hand.
Corrected entry: In Part One of this series As Stu leaves the Vermont Center For Disease Control there is Graffiti on the sign that reads "All Dead Here." When Stu returns to the center with some other survivors the sign is immaculately clean. (01:27:40 - 02:27:15)
Correction: The sign upon which 'All Dead Here' is spray-painted is near the street, and further out from the building than a small grassy area and a flagpole. When we see the sign 'later in the movie' that is immaculate, it is not the same sign at all, but one much closer to the building.
Continuity mistake: When Stu and Glen are about to meet Fran and Harold, Glen gets up out of a hammock to go and see them. When it cuts to a shot of Stu rushing to meet them, in the background behind Stu, you see Glen getting out of the hammock again.
Suggested correction: Glen at 1st sits up. Then he gets off the hammock.
I just rewatched that scene, and Glen does fully get up and out of that hammock twice.
Correction: It's not supposed to be his left hand. It's a left hand in a rubber glove of a right hand. The sound makes faint cracking noise and the fingers bend "backwards" on his fake right hand. It's just a poorly done special effect not a continuity error.
