      When using the attached datapack with some custom world generation settings, generating the world is incredibly slow. Normally, my computer can generate a new world fairly quickly. However, something about this makes it stay at 0% for actual minutes. This may be a problem with what I've done in the datapack, but I'm also fairly sure that it's a weird custom world generation bug.

      After letting it run for 10-ish minutes, it crashed with an IllegalArgumentException. I've also attached the crash report.

       

      EDIT: Added an updated pack for 1.18.2 - the world still doesn't load, though.

      EDIT 2: Added another updated pack for 1.19 snapshots - the world still doesn't load too.

       

      UPDATE: After some testing, it's the negative sea level that's throwing Minecraft off.
