Bug Description: When you knock a zombie down onto their back and then hit them with a killing blow, they snap onto their stomach and clip into the ground. Maybe a wrong animation path?
Detailed steps to reproduce the bug:
1) Knock zombie down onto their back.
2) Hit them while still down to kill them.
3) Watch them magically flip over instantly.
Actual result: Zombie clips into the ground out of nowhere.
Expected result: Zombie stays on their back and ragdolls.
Here is a vid from JaWoodle that shows it. He knocks the zombie down, and when he hits her again to kill her, she snaps from here back onto her stomach and clips into the ground:
