without the mod my poison zombies dont throw headcrabs :)

This is a pretty big issue. I have tested this, when i have it enabled, they just mindlessly run at me.
However when this is disabled, they will throw headcrabs at me.
So that means i have to choose between better NPCs or the NPCs do their job.
I would fix this, exept i have horrible lua skills.
pls fix

if its on or not it still wont throw

You have a addon that bugs your game

i have 0 addons

that basically is not possible.Are you sure your poison zombies dont throw poison headcrabs at you because it cant happen only of you messed somewhere up,tempered with the code,or have installed addons like this one
