• Ender pearls

• Blaze rods can't be obtained. They will need to be replaced with something.

• Blaze powder will be replaced with Sulphur.

• Glowstone will be replaced with Phosphorus.

• Netherite will be replaced with Gabro.

• Endstone will be probably retextured and used as some mineral or stone. Probably dolomite.

• Other stuff like chorus plants are still unknown what to do with them.

• The first two ones are pretty urgent. So they will be replaced in future.
  And the other stuff will maybe get replaced in future

Ok, I am gonna close this.
