After this patch I have witnessed the following problems with zombies.
-Zombies can run through walls and hit you from the other side.
-Zombies are nearly impossible to hit at times since the new patch.
-Zombies will spot you from 300 yards inside a bush.
-I will go into town and get ambushed by 10 zombies while inside one building in the span of two minutes.

I feel if you lowered the number of zombies or just simply made them harder to spot you this would make the game much more enjoyable to play. I understand this is a zombie/survival game but if I see a player in a town and I want to sneak up on him to investigate him further I shouldn't have to be distracted with 10 other zombies running towards me from 300 yards away. This takes away from player to player interactions if you are constantly spammed with zombie attacks.
