I'm having a similar issue. Not sure if it's related. Celene is no longer working at Grimtooth Bar.
One of my Sims married her. After, she has no job. I also replaced Grimtooth bar with a better version from the gallery. I moved the family out of my households but she still doesn't show up to work. The bartenders that do show up are wearing similar clothes as her. I had a sim sit around for multiple shift changes and she never showed up. How do I get her back to working there?
Edit: I should note, I'm not intending to play her or her household. I was just wanting to make a more fleshed out NPC household.
@Jeremy_GoneWild "One of my Sims married her." - as soon as any NPC special character is moved into a played household, they lose their special role and are replaced. They don't get it back if you mark them unplayed again.
The problem is Celene doesn't actually seem to get replaced? The other bartenders don't seem able to help with werebies.
Did you have her briefly as a played Sim for the wedding? You might be able to reset her with cheats: https://answers.ea.com/t5/General-Discussion-Feedback/Premade-sims-losing-their-occupation-when-played/td-p/10693448
For me the problem is related to the nighborhood storys they implemented. I had the same problem with the magic mentors, now her and almost with Rory and Lou as well. Even the night stalker from the curse was put into an empty lot and constantly replaced. My whole list of fhouseholds is full of night stalkers that I keep deleting and no - I didnt break the curse!!
Storys seem to use homeless townies and put them into empty lots and making them unplayed households or even mixing the households, this seems to delete their special/hiddentrait. My Volkovs where all split through random households. I never ever touched Celene or the magic mentors but found them in lots that where empty before. I even turned storys off but this "feature" still trashes every of my gameplays with important NPCs just missing from what they are supposed to do or getting replaced without the things that makes the NPC special.
Storys was the biggest trash they could do if they couldnt even prevent important NPCs to be affected. Making a new save doesnt help because storys, even when turned off, messes with my households and townies. I have no mods acitve that could affect stuff like this.
