Updated to 1.21.5 Fixed every item and recipe that broke due to universal text changes... and attribute changes.
Fixed a handful of swords that changed damaged based on conditions (deepslate, obsidian, etc) that broke due to a change to equipment.
Fixed swords that displayed text (sign and nametag) to have the updated text format.
Fixed all swords that use armor stands to display extra models (anvil, dripstone, amethyst, and a few others) to use the new equipment eNBT format.
Probably fixed some other things.
