Context

I do have connector, but the two mods I have loaded through it are very minimal - one adds some fluids and the other adds a visual indicator for bookshelves.

While in world, things handle just fine and I can play for quite a while. But when leaving my main area that has quite a big create area it can crash with this. My partner had the crash happen on their client as well when in my world and the world stayed open but they crashed out of game.

I'm not sure fully what causes it other then its obviously related to leaving/entering an area? This isn't my area of expertise.

On 1.20.1 switch to forge (version 47.1.43 or newer) since neoforge is unmaintained for that version and lacks methods added by newer versions of forge
