Bug concerning careers and promotions
When my sims go to work, their performance don't progress anymore. so my sims can not have any promotion. I have already tried to make them "work hard", to repair the game, chat with a bot to find so...
Does this happen with all your sims or just one sim? If it is happening with all your sims, try resetting your sims 4 folder and test in a new save game file and see if the issue occurs there also.
