knock back on poison/fast zombies is up 900000% when knifed and 100% when shot in the head, the infected zombies are still low when knifed/shot, pred class now moves faster then they should, zombies are spawning without there knife again from time to time, and when zombies parachute they move 10% faster then before now.
Dont know what happend but this is what I and others have seen since the update, also zombies are still spawning at 8:50-8:45 giving humans only 10-20 seconds to start to run on some escape maps.
