Can you provide a seed for the world which you experienced the crash on?

I cannot reproduce the issue
Maybe you should record a video of the crash occuring?
I am unable to reproduce the crash anymore after deleting the poi folder in the world folder. Besides, the game simply crashes upon loading the chunk which the entity is located in.

Can confirm for 1.16.4
Can confirm POI data mismatch crash in 20w49. Although I got this crash from activating a redstone contraption that uses pistons and composters in it
