Has anybody had any success in converting a Sim into an NPC (e.g. Maid, Gardener, Mailman, etc.) that actually functions? I recall managing to do this in the past to limited success, but whatever I did back then sure doesn't seem to work anymore.

From what I can recall, the Sim needs to be added to the correct NPC career, and have the appropriate roles applied. Unfortunately the commands to add these only work on active Sims...which is a problem as any NPC roles/careers are lost when the Sim is made active for any reason. I remember that I used to be able to have the commands work on other targets, but in my testing this no longer seems to have any effect on a Sim unless they're in the active household.

Just wondering if anyone else has any ideas? Would be nice to be able to customise our NPCs.
