As Tess and Logan are driving at about 1 hour 10 mins, camera switches from one to another. Sometimes they have seat belts on sometimes not.
When Logan is pursuing the killer to Connecticut, the exterior shots show the second cop car, Chevy SUV, behind him. In the internal shots showing Logan driving, there's no vehicle behind him.
Out at the farm with Logan Tess is wearing boots, but when she gets out of the car back in the city she's wearing heels. Entering the library she's wearing heels, but during the chase scene she's back to boots.
When Tess is showing the pictures taken from Lyle's files, she identifies a device as a WWII-era "Enigma Machine". Whatever that object is (and it appears to be a 1950s-era adding machine of some sort), it is NOT an Enigma device: which, among other differences, has a full keyboard.
No jewelry on display in the jewelry store.
Lyle tells Tess his girlfriend, a chef, has him vegan now. When Tess and her aunt go to the girlfriend's demo, one of the dishes she is preparing is eggplant Parmesan.
When *a certain person* locks Tess in the freezer, they close the door and then run out of frame as if escaping quickly. But their reflection in the glass reveals that as soon as they are off-screen they stop and stand there, watching the rest of the shot play out.
