Minecraft Version

1.21.1

What happened?

How to replicate:

1. Set up datapack directory according to instructions in the wiki
2. Create item tag for necklace and add item to values field
3. Set up necklace slots as directed (implementation here)
4. Launch game
5. Try to put the indicated item into the necklace slot

Expected: Item is placed into necklace slot
Actual Outcome: Item cannot be placed into necklace slot

Minecraft version: NeoForge 1.21.1
Curios version: 9.4.2

The tooltip does not show up as well. Changing the validation to curios:all results in the tooltip showing and allows me to place the item.
Thank you!

This is due to your directory being called items instead of item (item would be the correct name). This is a change from 1.20.1 to 1.21.1 and the documentation was only for 1.20.1. I've just now updated the documentation website, splitting the 1.20.1 information into its own version and updating the current version with up-to-date 1.21.1 information, including listing the correct directory for tags.

Thank you very much!
