So I've been following this thread for solutions to this problem and I tried out your suggestion @twmuse
The two problem mods were removed last night and I still had issues. Just booted the game up about 20 mins ago and tried changing the lifespan with a new family; saved then saved as and exited to main menu then resumed play and tried to play.
Then got this error message from Better Exceptions from TwistedMexi: cpp_message - [manus] Save failed due to Exception (ValueError: Value out of range: 9946980009475700379)
I honestly have no idea what's going on. I've played with Mods, without Mods after taking out Mods, Saves and Tray Folders and then deleting everything to make sure there are new folders for a fresh start. This didn't start for me until the Patch On August 2022 to fix the other patch. I really hope that someone can figure this out as the game is totally unplayable for me currently with all progress reverting back to Sunday when the Sim moved in; skills are gone job is gone and all relationships are simply gone.
