The following items are being removed from the unmodded version and are being put into a "modded group" due to not being in actual Minecraft:
E (319)
Taco (322)
Damage Block (324)
Poisonous Bread (325)
These items will be able to still be used (Poisonous bread was removed in 2.5 but still works)
The gamerule for enabling/disabling the modded items will be /gamerule moddeditems (0/1)
