Thank you so much for this. I was using Indie Stone for my aging control, but as that is no longer supported in AM, I had to find something else.  One question (and sorry if I have missed the answer somewhere) Is there a way to return a sim to their previous age?  Not a feature I have used much myself, but there were occasions (going back to sims2 here) where I missed someone aging up and so used a mod to age them down.

On further thought, scrap that question. If I have their aging suspended while I'm not playing them, then I'm not going to miss them aging up!
