Carl, I have your site bookmarked for Sims 4 as I used it in Sims 3 too. It helped me in so many ways. Thank you for your work and dedication. I know it is a lot to do.
The only thing that is bugging me is the Aspiration- Soul mate. My Sim has this Aspiration while doing a legacy so I can't change it. It is unable to complete because she can't propose to her current husband again after making him her BFF. Also Marry your BFF didn't update after making them BFF's, however I made them BFF's after they were married not realizing this was a future requirement. Guess I should have checked the whole Aspiration panel before getting married. So I guess this is another bug we have to wait until it is fixed.
So, that might be one you have to put on a back burner for now.
