I have an issue where my autonaut is programmed to get water from water storage, add it to a crude wash tub, and repeat indefinitely. Sometimes when the tub is being used to clean something, the water doesn't get added to it, but the autonaut thinks it does. It then tries to refill the bucket already full with water and gets stuck.
If the autonauts could tell the difference between an empty bucket and one with fluid in it, this wouldn't be a problem.
