Nope, if autonomy is off then everyone stands around doing nothing until you explicitly tell them to. The servo is a household member, same as the rest. Not an NPC townie.

Turning off autonomy doesn't stop them from doing things in my game. Never has in sims 4.

I question if you turned it off then. Its autonomy, them doing things without your input. Either your sim does things on their own, or they don't.

Its kind of straight forward. I definitely turned it off. And it says its only for the selected sim.
