Any creature has the probability of disappearing as it passes through the block, even if the player is nearby, even if the player's equipment is worn

Zombie pig man killed me, I was reborn near the death point, and when I ran back, the zombie pig man in my gear disappeared before my eyes! Top armor and the next alloy sword! I'm really upset about this bug. Minecarts are entities that will disappear at a rate as they pass through the blocks, which can cause some machinery to fail! Hope to fix this vulnerability earlier!
