I was walking through the nether, and found a piglin that seems to be frozen. I am unable to hit it, make it fall, or throw it with knockback. My friend that was in the world was unable to see the false entity. Once I left and rejoined the world, the entity no longer existed.

I also experienced this bug before when shooting a villager with punch two arrows once a creative world. Once I rejoined it, the villager switched positions and went normal again.

I am not sure how to reproduce the issue.

I have two videos that show this issue, I am unable to put them here as they are over 10MB, so here they are in links: https://drive.google.com/drive/folders/1oXnpIGzObjI5fTv9flESoYh58kY2ykLX?usp=sharing
