In researching the wiki, I’ve found a few NPCs that seem to be unspawnable via admin panel, both single player and online. The IDs are there, but characters will not spawn.
- Ansina Hidden-Daggers (Darfari_Cannibals_Entertainer_4_Darfari)
- Maru the Cannibal (Darfari_Cannibals_Cook_4_Darfari)
- V’anarr Feasts-On-Fingers (Darfari_Cannibals_Cook_4_Darfari2)
I have never seen these characters spawn at their listed spawn points, but the wiki has images of two of the three.
