java.lang.IllegalStateException: POI data mismatch: already registered

This crash happens whenever I enter a certain part of the world.

 

How to reproduce:

Approach the coordinates listed in the crash report (x=1071, y=15, z=-465). The crash will then occur as the area is loaded.

 

Workaround:

Access the world folder in .minecraft/saves, and delete the poi folder.

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.

Thank you for your report!

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
