Zombie pigmen can break down doors like the old zombies
What I expected to happen was...:
The pigman would wonder around like normal
What actually happened was...:
He approached a door and started to smash it with the well known very loud door breaking noise.
Steps to Reproduce:
1. Make a box
2. place a door as the only opening
3. Spawn zombie pigman and watch the magic or give him a nice punch in his rotting zombie face so he tries to kill you
Zombie Pigmen share code with regular Zombies so this isn't surprising. Maybe this is intended behavior?
Regardless, it probably doesn't work with ALL zombie pigmen. DB changed the code for zombies breaking down doors a while back. Now, only a percentage of zombies can do this whereas when first implemented all zombies could.
