Infected got broken again after today's update :(

-They're pushing the character A LOT.
-Their speed is like x3 of what it was before
-They see through textures, impossible to hide/sneak from them at times
-Sneak mechanics were disabled? They see camouflaged characters from a big distance, even if it's crouched!
-Aren't able to hit players that are prone again
-They die from 1 shot in any part of the body o.O?
