During an interview with Adam Clark as both he and Lilly are smoking, one shot of Lilly shows that she's about to take a drag.
In the next shot only a second later the cigarette is nowhere near her mouth. Instead it's closer to the table as if just coming back up from the ashtray before she even took the drag.
From the side of her head the viewers would have seen her take the drag if it was a constant shot even from another camera angle.
When they read the address found in the airtight pouch, they say it's "4912", however when Lily and Scotty go to the address, you can clearly see they knock on (and enter) 4811. You can also see on the green building next to them the address 4813....Lily and Scotty are clearly on the wrong side of the street.
