So, there it says I have 3 members, one of them doesn't have a health thingy on top, and I can't change the job of Duke, the guy with the black hat
Duke is a companion. Right click on him and we will follow you around and shoot things. He doesn't work. The three people are you, Duke, and the other guy. Only the other guy can have a job.
Also the health bar only appears if the worker is hurt.
