Bug Description:

* a single file line of zombies was heading toward me, with a snake a few meters in front of them. The 1st zombie in line dropped down to eat the snake & i killed the zombie (headshot). The 2nd zombie also dropped down to eat, and appeared to be having sex with 1st zombie, i killed it. The 3rd zombie in line dropped down slightly behind the 2nd zombie, to eat, and also appeared to be having sex with the 2nd zombie.

At first i wasn't sure what was happening, until i realized the zombies were trying to eat the snake, and there was just an unfortunate appearance caused by the feeding animation - the feeding zombie appears to move forward & back, while down on all fours, giving an unfortunate visual result if there is a zombie corpse in front of them. They were in a l8ne, and very close together. There were also some clumps of grass around them. Also happened to be at night, while i had a headlamp turned on.

Detailed steps to reproduce the bug:

1) kill an animal, while a single-file line of zombies is heading toward you, and dead animal between you & zombies

2) when 1st zombie drops down to feed, kill it

3) when 2nd zombie drops down to feed, it will often be just a bit beh8nd the first zombie

4) observe resulting animation

Actual result: (description of what is occurring)

* feeding animation makes it appear that the zombie currently attempting to feed on the dead animal, is having sex with the zombie corpse in front of it

Expected result: (what you expect to occur)

* seriously, anyth8ng but that. Not sure what the best solution would be
