Added mythic change GUI, with new apply item use method: GUI! You can now use apply item in a GUI and change the item, in future, MythicChanger can become a gem plugin with more feature added!
Fixed HIDE_ATTRIBUTES item flag does not work for item does not have attribute modifier in 1.20.6 and higher version.
This is a bug from Mojang and we can do nothing for this. Plugin will auto add empty attribute modifier if you add hide attributes flag to solve this problem.
