I was hoping I could get some help with this weird crash. I've hosted many servers before and never had this issue.

Now and then the server crashed with "Exception ticking world". Everywhere I looked I rarely found any info on it (usually found ticking entity instead).
Any advice I did get (mostly from the modpack owner's discord) was "We don't know and it's near impossible to find out what it is".

Here is the crash report:

If you want the full version, I can link a pastebin if needed.

Some helpful information is that:

It seems to only happen when I leave my void world to enter the overworld.
Only happens 5-10% of the time.
Only happens when leaving the void world, and only the void world.

I know it's a slim chance someone could help, but it'd be greatly appreciated.

Also add the latest.log from /logs/

Here is the end of the log. it was way too big to put in pastebin, but I started from when I was online and everything was fine. Error should be in here:

Maybe an issue with ebwizardry

What in particular? I barely used that mod this time around, and it's never been a problem in the past.

This is the last line before the crash:

[ebwizardry]: Synchronising spell emitters for PixelTraveler

But I have no idea what this means

that happens every time I enter a new dimension.

UPDATE:

This seems to be happening every time I leave the Beneath dimension (2 for 2).

Not sure why those 2 dimensions specifically. I have no problems with the nether or Twilight Forest.
