I think there might be an issue when using this mod together with the Get Famous Actor career. I’m also using it alongside the Career Overhaul Suite, to make sure co-workers are generated, but I’m still running into problems with co-stars generation.
I first noticed this when inviting the director and co-stars over. Sometimes only the director shows up; other times it’s the director and just one co-star instead of the usual two. I’ve only been using this mod for a few hours and this has already happened several times, including cases where I couldn’t finish filming because only one co-star was on set.
