Hello! Currently making some configs for RPG, but using 'locked' on vanilla items doesn't seem to work very well. For example, in the Official RPG configs items here, the 'Diamond Armour' and 'Diamond Sword' locking doesn't work. Diamond Armour can still be equipped inside the inventory, and the Sword can still deal damage as a weapon.
I think the reason for this is that 'Locking' an item only prevents Right-Clicks. As the 'Not Trained' message only pops up when the item is right clicked, and vanilla items like bows and crossbows cannot be fired, only drawn.
On the bright side, I have many new rpg spell configs I can share soon! Thanks in advance :D
