Corrected entry: Before Tina makes Melissa's pearl necklace fall apart, between shots the necklace changes position.
Corrected entry: In the scenes from the previous film used as a prologue, Jason is drowned in a green jacket with some kind of utility belt. However, when the film begins in earnest with the little girl on the boat, Jason is seen in a blue jacket without the belt. Normally this being a difference between one movie and it's sequel it wouldn't matter, but they showed the prior film in a prologue.
Corrected entry: When Tina arrives at the cabin she is wearing khaki pants. Then a scene following where she moves the matchbook she is wearing blue jeans. Then when she goes to the party and when she frees Jason she is back in the khaki pants, then the next day she is back in the blue jeans when she defeats Jason.
Corrected entry: If Tina's dad was accidentally killed at the lake when she was a young girl - by her telepathic powers - wouldn't her dad's body be recovered, given an autopsy, and then buried? How does he spring from the lake to save her at the end? Why is his body so well preserved?
Corrected entry: At the end of the movie, Tina's father rises out of the water and grabs Jason. The problem is he pretty much looks like he did when he died, it's several years later her father's body would be very decayed.
