*le sigh* Fine:

The fact that I can look through a scope from a rooftop in all directions and there isn't one zombie. I take three steps and suddenly Here comes one from way off in the distance, sprinting full tilt towards me when he had no business beign able to detect me from across several acres of wood and fields.
I have even been attacked by zombies who sprint at me while SPAWNING IN, before I even move!

I know this has to have been reported before
