      Description

      Hi,

      I was trying to use huge mushroom features to generate non-mushroom blocks in a world-generation datapack. However the game refuses to generate these blocks and crashes because it tries to set a property which does not exist on the block.

      I have attached the crash, the datapack and the offending feature (`crash_mushroom.json`).

      How to reproduce

      1. Install the Incendium v2.6-crash-edition.zip datapack on a world
      2. Navigate to coordinates (300, 64, 300) in the nether
        /execute in the_nether run tp @s 300 64 300
      3. Observe the game crash
