Deactivate Servos...

When I play another household and come back to the household with the Servo, the Servo is going into catastrophic failure and I have to cheat its needs back up before death. 

Servos can also feel excessively needy at times and a break from them without moving them out of the household or having to destroying/deleting them would be nice. 

An off switch that puts them in stasis kind of like when Patchy goes dormant. Maybe have them return to the robotics workbench and shut down.
