University Life - Bugs

Hi. I think it's University Life stuff because when I finally made my ServoBot, I noticed something. They got sick. From the Get To Work sickness system, I'm not sure if that's meant to happen, but it's something I've noticed. Considering they're immortal in every other way apart from being maintained, I found it odd they felt nauseous as a robot. I would understand if there was the final upgrade to become a real-life sim, which would be cool. And yes EA team, I'll post it on the Bug Forums too, just wanted to see if anyone else had this issue or if it's just me.
