Actions to reproduce (if known)
I assume this crash is caused by the boundary between new and old chunks. It is caused by the generation of a certain fireball.
The trigger of this crash is the Oh The Dungeon plugin. But as the author of this plugin claims:

Paper version
This server is running Paper version git-Paper-140 (MC: 1.18.1) (Implementing API version 1.18.1-R0.1-SNAPSHOT) (Git: d9fb602)
