California, Here We Come! - S4-E13
Revealing mistake: The Pontiac's glass windshield is gone when the car is loaded down with everyone's stuff, thanks to Fred's packing, and the windshield is also very noticeably gone when they all finally drive off. The rearview mirror, which should be attached to the windshield frame, is gone as well. (00:20:30 - 00:22:50)
Suggested correction: BB-8 is heading towards a background at night, the other instances are all near where BB-8 is since they are all focused around him. Rey finds BB-8, only possible if she is near the same background. BB-8 was going towards that background so can only be closer to it than before. Same goes for Finn as they crashed near where BB-8 was, since they were looking for him. They are not the exact same locations but a couple of miles apart, which produces the same background.

When Rey rushes toward Teedo and then when she walks away in the opposite direction with BB-8 the very same sand dunes are still in front of her and BB-8. Those sand dunes are also the exact same sand dunes right in front of BB-8 when he left the village. The correction states "They are not the exact same locations but a couple of miles apart", but they are in fact the exact same sand dunes and hills, certainly not miles apart, and I do not mean the general horizon "which produces the same background" (screenshots available).
