Thank you so much!
I also had problems sticking with one save so I decided to make three completely different saves: One with a legacy, this legacy (it makes me change the main characters and storylines so I don't get tired of the same sims), One with the same Sims since 2017 (this one makes me stick with the same sims; It's mostly my completionist save, and my main save to be honest), and finally a "Test" save, it's a save where I put the sims I use to try new features or, features I rarely use but it allows me not to abandon those sims once I finished playing with them😅
