Looks like I've given it a Summon tag, I've assigned it equipment, stats, and skills. Lootable is disabled as well. I'm not sure but I think it's not pulling something from the database because I haven't copied it over?
I didn't get this error until I reloaded my project, so if you want to replicate it I would try saving and reloading your project to see if that same happens to you.
