Write Song / Book / Lyrics Loses Progress

This bug has been in my game since the release of Growing Together in 2023. Mods or no mods, uninstalling then reinstalling, nothing has changed in years for me. All progress on books and music are lost after a loading screen from CAS and/or traveling outside the home!. My Sims only write short stories and children's books, so they can be easily finished in one sitting. Sometimes I'll use mods to turn them into Homebody Sims that don't like leaving their house and avoid opening CAS until their book is done (if I can remember😭). As for music, none of my Sims have written a finished song in years!
