Steps/models to reproduce
Just started the server
Plugin and Datapack List
None
Paper version
Paper 1.19.2 build #132
Other
No response
Just wanted to say your issue says build 132 but your log says git-Paper-81, which is a difference of 51 builds
can you provide the world this is happening in ? Replicating this seems pretty horrible :sweat:

Well I thought Ive used the latest build.
If you can, just throw your world folder into a zip/tar.gz and upload it here. if it is too large for github, maybe test if this is a specific issue based on the seed (e.g. if you create a new fresh paper server with the same seed, does this error also occur ?)
Last option would be some file share like google driver.
I fail to replicate this on my local setup using the latest paper. Can you attempt to test this with your local setup on the proper latest paper version, 1.19.2 build #132 ?
I don't recall anything touching this area, however having a shared ground for testing would be useful.
The general issue seems borderline impossible to run into, at least from my first look at the code that is erroring if you are not running any plugins and not-modified paper.
Seeing as though we haven’t had similar reports to this, I’ll be closing this.
If you are still able to reproduce the issue even with taking the above comment into consideration please feel free to comment and this issue can be reopened. Thank you 😄
