Could you test on a backup just to see if it works with that one too, for science ? Rejoining should put you on one level lower then you were before.
Did you also try turn on/off the following message ? I would save under new name and restart the game before switching it back on.
Yes, I made sure the follow option was enabled.
Looks like rejoining the career fixed it, and I luckily didn't lose my Sim's trait or career progress. She immediately went back to level 10 of the reaper career when I had her rejoin.
I don't know what caused this issue. Sorry if it wasn't anything worth making a report about. I just didn't know what was going on and it was frustrating trying to deal with it. At least I found a fix. I just hope it doesn't happen again.
