Hello.
I've noticed that both the default and custom knockback resistance values from the config aren't showing up in the game, as it should be like with netherite armor. I tried to change, for example, from 0.1 to 1, but nothing.
I'm using latest version 1.3.39
I tried to attach a screenshot with the default knockback resistance and custom armor hardness values in config.

Will be fixed up in the next update.
