When officer Chandler shows the councilman the staged video of the casino owners calling him short and still running a casino in another location, the video was filmed in the old house as evidenced by the stairs and carpet. This could not have been done as that house was burned down at this point in the movie. Also, it was clearly not a different location as was stated in the scene.
When Scott has trouble recalling the combination to the safe, Kate encourages him by saying that he can remember 4 sequential numbers. When Scott does remember the combination it is 8 numbers plus #. Then the combination punched in to open the safe beeps 7 times, which means only 6 numbers were entered with the # sign.
Granted the movie was filmed prior to the 2016 election, it takes place in the summer of 2017 between Alex's graduation from high school and start of her freshman year at college. The Johansens state several times that they have a month to make Alex's tuition money. According to the financial statement Scott & Kate receive in the mail, the tuition is due on August 20, 2017. So we can presume that events in the film take place during the Summer of 2017. However, in one scene to test his sobriety, Kate asks Scott who is President. He mumbles Barack Obama, which Kate seems to affirm. However, Trump would have already been inaugurated President in January 2017.
Officer Chandler questions why Frank is walking in the woods. However as previously established in the film, the woods run alongside Frank's property - so it would make more sense for Frank to question Officer Chandler's being there.
There is a running joke throughout the film that Scott is bad at math and has a fear of numbers to the point where he has trouble with basic math and freaks out whenever another character uses numbers. However, in one of the very first scenes while touring Bucknell he tells Alex that you should drink one bottle of water for every bottle of beer and equates a 6 pack of beer to 6 bottles of water. In another scene, Scott mistakes a 401K account for $401,000 which means he can equate the letter "K" to equal thousand and equates 401K to 401,000. He also uses the term "86" in another scene - a term someone who has a fear of numbers, would be less than likely to use.
