I have a Sim who is a Level 10 Doctor, yet her Research job metric is and always has been on the 'neutral' face. She has 2 'medical journals' in her inventory, but no matter how many times she reads them, the research metric stays the same. I have never played a doctor this far before, so I do not know if she is supposed to be getting new journals to read or not. Am I missing something obvious or is this a glitch?
