I tried giving a certain group permission to add a specific group (called builder) which didn't work. Adding the permission luckperms.user.parent.add works, but is not desired as it allows to add all groups when I tried luckperms.user.parent.add.builder which didn't work, it would just say [LP] Running LuckPerms v4.1.54.

I tried running verbose to see if I was missing any permissions, but verbose appears to list basically every permission included by LuckPerms.

Are there any additional permissions that need to be added? Or is this a bug?

Is the setting argument-based-command-permissions true in your config?

It wasn't. Setting it to true fixed it (also fixed verbose listing all permissions).

Thank you for your fast response!
