Other mistake: When Helen turns right to "head to the stacks" everyone in the back of the van falls to the right. Centrifugal force would push them to the left. (01:56:06)
Other mistake: After Wade gets the second clue, he's shown in his little hide away spot looking over a notebook he has wrote in with the words Clue #2, a large number 2 out next to that, and under it in quotes "A creator who hates his own creation" with a hand drawn box around creator. This sentence is highlighted and there is more under it. This is a hand written note on a spiral notebook that he just got after getting the second clue which had only now been revealed. So he sets the notebook in his lap and starts looking over the newspaper clippings and other papers on the wall about Halliday. As the camera pans over, you suddenly see the top of the same paper torn and pinned to the wall. The hand writing is exactly the same, the boxes and figures drawn exactly the same, and is only missing the orange highlights over it. The paper is wrinkled a bit and shows the holes from the spiral as it was torn out and pinned to the wall. But this is impossible as he still has the same paper in his hand, and he only just now got this clue. Somehow a duplicate is on the wall already. (00:34:20)
Other mistake: When Wade is explaining his past at the beginning, he says he was born after the corn syrup droughts, after the bandwidth riots, after people stopped trying to fix problems and just tried to outlive them. Then he says his parents didn't make it through those times. So, how was he born?
Suggested correction: From a military point of view it makes perfect sense. AOE weapons would be most likely to hit members of the same squads, companies or battalions. It would make sense for squad mates in the oasis to stick together in stations as well. I just watched that scene. As long as the Sixers are trained soldiers or players it makes perfect sense.
