(00:26:30 - 00:28:35)

Continuity mistake: When Jason throws the machete through Kay-Em, the machete's angle changes position between the shots. (01:03:00)
Continuity mistake: When Kay-Em jumps on the platform while attacking Jason, she is shown crouched down and says "Hey." and she is missing her black latex gloves, but in the next shot the gloves are back on. (01:03:30)
Continuity mistake: After Jason throws his machete through Kay-Em, you can see behind Jason there is a tunnel, which they are both outside of. When Kay-Em starts kicking him they are both halfway through the tunnel. (01:03:40)
Continuity mistake: When Kay-Em is shown firing at Jason with the two pistols her arms are straight out in front of her, but in the shot from below her elbows are bent and she's firing from waist height. In the next shot, her arms have returned to being straight out. (01:03:45)

Continuity mistake: At the beginning they show a close up of Jason, the skin around his eyes and ears (around the outside of the mask), are flesh colored and looks like normal healthy skin. When Adrianne takes his mask off during the autopsy they skin is grayish like it's decaying.
Answer: Jason wasn't deformed as a child. Jason was deformed at birth. His regeneration can't fix anything better then it already was, just to where it was to begin with, therefore since his face was always deformed it can't be fixed better than its deformed state. If half his head is blown up it will regenerate, but only as far as the deformed state.
