Here's a video showing the main issues I am having with AI at the moment, it's more obvious with melee range characters like the zombies, as you can see the pathing is just not right, at some points it goes off on a tangent and tried to enter a side room to path to me when i'm around a corner, other times it just gets stuck and loops sound and animation on the spot, it also sometimes just stops for no apparent reason until I take a few steps forward, and finally at the end it completely freeze up and stop working.
