Happy Death DayGoofs
When Tree shoots Tombs, she fires only three rounds before the slide is shown locked back. This indicates that the magazine is empty at that point. This pistol carries more than a dozen rounds in the magazine. No officer would ever carry only three rounds in their magazine, the magazine would be full.

Errors in geography
When the police car is side swiped, the black charger shows no damage to driver side at all. It should have scrapes or broken mirror. As the fire starts in crown victoria, the gas is bubbling up around fuel door gas wont bubble up and there would be gas cap in way if it could. The gas would have to come from behind body panel, but damage was not enough for that.
Incorrectly regarded as goofs
It doesn't seem to matter how soon Tree decides to leave the dorm room after waking up. Even when she rushes out of the room, Carter's roommate shows up right away without any regard to the original conversation . The environmental girl still walks up to her at the same time the sprinklers go off at the same time, the frat guy falls down at the same time, etc. In case Tree leaves the dorm so quickly, she should be ahead of all of these events.
During the last day from the loop, how could Tree have the time to get close and so friendly with Carter, after leaving so quickly in the morning? Isn't she supposed to spend time with the police for interrogation or/and probably get arrested for murder charge against her roommate Lori, until the situation is clarified and she is exonerated? Instead, she is free like if nothing had happened.
At one point, Tree plots out a way to kill Tombs. She goes to the hospital, pulls a knife on the officer, takes his gun, tells him that Tombs is about to escape and to go get help. She then goes into his room where he escapes, they fight and she shoots and kills him. She's then seen celebrating her birthday. There is no way that she'd be free that night - she would at the very least be charged with the murder of Tombs since there's no witnesses to see that he did in fact free himself. From an outsiders point of view, she took an officers gun, untied Tombs, and then killed him.
