Hitboxes of HEV zombies on legs are wierd

So, HEV zombies invulnerable to bullets while shooting in body but not in head, seems work as designed. Well, with legs if you shooting in right leg, it’s still invulnerable but if in left leg, it’s not. It looks like damage shouldn’t be dealt because it’s part of the legs but I don’t really know.

Blue sparks showcase what damage have been dealt.

look closely at the model there is a hole in the suit there. Other then that no clue.

If you talking about hole on the right leg, it’s because of shooting in it. Also left leg is vulnerable to damage.
