Paradise City

One time, I heard someone say that zombies weren't attacking him. I didn't take it seriously until it happened to me. I'll try to be specific. I was walking around in Zombie Forest. killing zombies, when I noticed it seemed like zombies weren't even attacking me. I turned autofire off, and they weren't. They were just wandering around like I wasn't there. I knifed some, threw a grenade and shot some, but they still just wandered around like normal. You can obviously see how someone could abuse this bug.
