      The error message that occurs every time I try to create/load a world with a custom dimension is:

      ---- Minecraft Crash Report ----
      // This doesn't make any sense!

      The files test1.txt and test2.txt were used to test world creation after loading 1.16 pre1. worldgen_settings_export.json is the file I used to create my Redstone Testing world. I had to manually remove the dimension using an nbt editor in order to be able to get back into that world. I also had to remove the extra dimension's nbt for my survival world too.


      The survival world had a caves dimension generation which I used to simulate a cave update for the time being.
