Just to add: I'm not some magical know-it-all. Quite the contrary, there are still many options in the NRAAS suite of which I'm not sure of what they do, and I'm sure there are other game options I don't even know about. This "forgetting to register career" is something I regularly do with my plumbots, because they don't have the trait chips that makes it possible for them to go to work. The game will send them somewhere, anyway, because inactives can skip all prerequisites. Or I do something of which I don't consider all consequences. I once told Register to use townies for roles, and I was a bit in a pickle when my, this time properly registered as "unemployed", nannybot was recruited to man the kissing booth during the spring festival. Oops. It was funny though. She didn't earn a single simoleon though. I wonder why :p Then it was also babysitter time, until I found the place where I could get the bot out of that role again.
Fortunately, there's an inbuilt plumbot caste that allows for at least a few settings.
