Plot hole: The team starts to break into the Pierson building from the roof. But how did they get to the roof? It seems to be a pretty high stand-alone building.
Suggested correction: This is a question, not a plot hole.
It's a plot hole phrased as a question, perfectly valid. Given there's no obvious answer it makes more sense to have it as a plot hole, otherwise it's a question which gets the answer "there's no answer, it's a plot hole" and then gets listed again as a mistake.
I disagree. Not knowing how a character got to a certain location doesn't constitute a plot hole. There are many reasonable explanations for them getting onto the roof. They're professional criminals, and one of them is a cat burglar.
