This is an update to fix the Policewoman zombie.
Unbeknownst to me, people were commenting on other sites that the Policewoman's head hitbox wasn't working. I confirmed that the collider on the "Head" object wasn't working.
It turns out this is because I used the "Head" transform as the "RightHandJointName" transform, so that the cop vomit would originate from her mouth, rather than her hand. What I didn't know is that transforms used as weapon joints, as well as their children, apparently have their colliders disabled.
I fixed it by adding an empty "Jaw" object, as a child of the "Head" object, and using that instead.
I also fixed a couple of minor issues with the AI targeting, though I don't think anyone noticed these.
There should be no risk to save games if you are updating from 2.0.1.0.
