Yeah I agree and found this as well. I did the same as you using MCCC to lengthen the adult agespan, but I've also upped the YA agespan, so it's about 35 days - enough time to finish university if they do 4 terms, and it gives them an extra week to live normally as a YA. I've found it has helped quite a lot because it gives them a bit more time to find a partner and have children, so they don't automatically die when their children become teens! :s I've also lengthened the elder stage by a couple of weeks, so they might live to see their kids graduate from college. Sometimes they can live to meet grandchildren with those extensions...but it's still quite rare and really needs their children to have children pretty close to turning YA.
