Minecraft version: 1.20.6
Modloader: Fabric
Fabric loader version: 0.15.10
Environment: Singleplayer and Multiplayer

Mod name: What Durability?
Mod version: 1.1

Description
Although no items have durability, no items can be combined in an anvil anymore. Trying to combine two undamaged items does not work in an anvil, and coming two enchanted items does not combine the items or the enchantments.

To reproduce, go into creative, place an anvil, enchant one sword with sharpness and the other sword with unbreaking. Try to combine both swords in an anvil, it will not work. Hopefully this can be fixed.

Here's a similar mod that fixed this issue already, but they are slow at updating and don't have a 1.20.6 version available: https://modrinth.com/mod/nodurability/versions

Closing this as it's a duplicate of #2337.
