Continuity mistake: As Rey is retrieving her staff with a slimed BB-8 in her grasp, she passes by and leaps onto the leg of an old fallen AT-AT Walker which is next to her. There is a fin sticking up into the air from its foot with a groove down the middle in the close shot as she gets her staff. In one of the following shots as she's jumping up onto the leg, that middle groove on the fin disappears. Also in these shots, suddenly much more sand is built up against the foot of the Walker than before. (00:02:00)
Continuity mistake: When Danny and Ward meet Joy in her new place, Ward says "who was it who said I was being childish?" Danny is in the background, holding the folder cover open with his left hand. Shot cuts as he speaks, and his hand's suddenly on the pages with the folder cover hanging down loose.
