Audio problem: When Cher and Tai are at the party and Travis comes up to them he has 2 cups of some kind of drink and all of a sudden you hear a sound that is supposed to be something spilling. I guess they assumed that it was supposed to be the beer spilling on Cher's shoes. Well as you can see nothing falls/spills from the cup, it is just sound effects.
Audio problem: In the scene at the party when Tai sits up after Elton placed her on the table she hits her head on a light hanging overhead. The sound the bump makes is not consistent with someone hitting the light with their head in such a manner. It appears that it's just a sound effect added in. (00:37:30)
