Re: Director, stylist and co-actors missing from acting job
I actually played my Get Famous actor sim yesterday and did two gigs and they were completey fine. I've done almost all of the gigs and I've never seen the makeup artist, director, stylist or any of the other critical sims like co-stars leave the set.
It's hard to say what could be causing your issue, but since I'm not getting it, it's most likely something you've got on your end. In your video it shows you're using MC Command Center. Are you sure there isn't some setting you've got active that's causing this? Even if you remove all mods, they may have caused permanent changes to the save file, like maybe the game never created a wardrobe stylist or makeup artist in the first place.
Have you tested to see if this happens in a completely fresh new saved game with absolutely no mods installed?
