Max and Caroline accidentally leave three envelopes behind at the prison; one was Sophie's baby's gender, one was Caroline's "wallet", and the third was Caroline's "makeup bag". When Caroline returns to retrieve them, she only gets back the baby gender envelope and the makeup envelope.
The slice of cake Sophie pulls off the cake is not intact at the bottom, then the next shot of the slice shows it fully intact, then the shot after that it's not intact at the bottom again.
When Max accidentally hits Han with the cake batter and he exclaims that he has an egg allergy, the next time we see him, which couldn't be any later than a day, he shows no signs of the allergy, which even after a shot or whatever treatment he would need, he would still show "battle scars".
