Custom Anvil now does not require ProtocoLib to override Too Expensive for minecraft version 1.17 to 1.21.1
If you encounter any issue related to this or just want to use ProtocoLib instead of the built-in packet sender , you can add/set in config.yml

ProtocoLib will still be the default on unsupported version (1.16.5 & over 1.21.1 on release on a not updated version of the plugin)

Bug fix:

• Custom Anvil craft could make item disappear if player do not have required level on creative.
• removed xp level on custom anvil craft did not depend on "xp cost per craft"
