Hey, getting back with a response, tried the steps and yeah it did wipe the NPC off.
Have just opted to run it via Comp/Con instead in the meantime, since I can't find whats making Owlbear not accept the NPC json properly (re the unknown systems as well.)
Still thanks for the assist, this LCP is one of the few I like the most due to the options it brings to the table and the sheer variability I can do with NPCs with it.
