• Automatic compatibility with Nether height modifying datapacks/mods that don't properly declare their logical height
  • Which is all of them, as far as we know
  • This includes Incendium and Amplified Nether

If you have been using the "Amplified Nether Height" fix datapack we previously recommended:

• with Amplified Nether: Keep using it. It fixes vanilla bugs as well.
• with Incendium: Remove it, as it's designed for a 256-height nether and Incendium is 192-height (we didn't know they were different until today). Leaving it installed makes Chorus Fruit put you on the Nether roof, among other issues.
