Steps to reproduce:

1. Start Singleplayer
2. Create materials to craft Mana Band
3. Craft Mana Band
4. Equip Mana Band in Bauble Ring Slot

What I expected to happen:
Mana Band would equip as normal and work as expected

What happened instead:
The game froze briefly upon equipping the Mana Band and proceeded to crash. The world can no longer be accessed without uninstalling Botania or finding a way to edit player data to remove the Bauble.

fixed in the next version of botania, downgrade baubles for a workaround in the meantime
