Known Issues

  • The thick green fog from the Slimy Sewers, the yellow fog from the Limestone Caves and the blue fog from the Luminous Caverns, Ice Caves & Soul Caverns also appear on the surface.
  • Due to technical limitations, Radiant Vines, Dripping Slime, Sandy Roots and Dripping Icicles will not break when a supporting block is broken.
  • Blocks with a custom model (e.g. Radiant Vines & Dripping Icicles) do not get destroyed by water or lava and are not able to be waterlogged.
  • Pick Block does not work on blocks with a custom model. Get them from the inventory instead.
  • Some errors may show up when generating a world. These errors do not affect gameplay in any way and can be safely ignored. To turn off the error log, go to Settings > Creator > turn off “Enable Content Log GUI”.
  • World generation may take a bit longer when this add-on is activated.
