Have you seen any mistakes on Heroes that they didn't edit out

The ones i've seen are:
When Peter travels to the future, Knox is behind little Noah holding him under he's throat. But in another scence Knox is beside him with his hand on his shoulder. But when the camera goes back, Knox is behind Noah again.

Also when Claire gets the job at the comic
book store, her hair is curled around the sides. But when she's out in the street, the sides are stright.
