Not sure where this belongs but I'm trying to access the config for opticsmanager ingame with the /cmdconfig and get thrown a error on client and server. I am running Spongeforge and LuckPerms, I set the node creativecore.*

Can you show me your mod list?

Fixed in the newest version of CreativeCore.
