Astronaut Career broken?

Hi, my Sim is on level 8 of the Space Ranger career (Planet Patrol). Until the update she's moved up every couple of work days and now... nothing. She meets all requirements for level 9; fitness and rocket science, she completes her space exploration daily task, but hasn't moved on in weeks. Even the job performance needle hasn't moved from Average performance, although they keep giving her raises and bonuses, just not promotions. Has anyone else encountered this? She's living in Strangerville. I have absolutely no mods or CC.
