In 1.12 when hitting an infected from behind to perform a 'stealth kill', there is no longer an impact sound played for the weapon striking the infected with either a light or heavy attack:
I have tested with the splitting axe, hatchet and fire axe but I believe it is an issue with all weapons.
Equip a sharp weapon
Sneak up behind an infected
Attack them in the head from behind
Observe the lack of weapon impact sound
Hello crazyjoe101.
The issue has been confirmed and scheduled for a fix.

Hello, I have also noted that the zombies will fall backwards towards the player 100% of the time, while the natural way to fall for most weapons would be forward on their face.
