The 1.16 update is here and I still have pigmen in my game instead of zombie piglins

Zombified Piglin replaced by zombie pigman in nether update versions causes conflict between "zombie_pigman.entity.json" and "zombie_pigman.v1.0.entity.json" file at entity folder in minecraft default resource pack. So i knew how to fix that bug. Just make sure "zombie_pigman.v1.0.entity.json" file code is overwrited by this code :
