Unknown Failure
I have already lost all my saves and Uninstalled and reinstalled rhe entire game and packs. (I did a backup file, but I beleive it was deleted in the cleaning of residual files accidently) 960 hours...
@SativaSunshinee Please uninstall and reinstall only the Parenthood pack. It has its own folder in [install location]\The Sims 4, here by default:
C:\Program Files (x86)\Steam\steamapps\common\The Sims 4
Parenthood is GP05. You can simply delete the folder.
If that doesn't help, please list the items you're having trouble with, or at least a few of them, if it's not every item from the pack. Please also include screenshots of the two errors, for reference—if this turns out to be a Steam or EA side issue, screenshots may help the investigation.
