Really hope the new milestones were getting will be as good as the Sims 2s memory system

I hope they are better, I have loved sims a long time and have always been good with as long as I can play, the bad isn't an issue. However I remember some game breaking bugs with damaged memories I remember if a Sim had something wrong like a kid getting one that only an adult would have that was leading to Uninstall re-install corruption ? . Excited to see how it goes.
