Hi,
Yes it’s every household that I have previously played and have a save with but creating a new household in CAS from the main screen works fine.
I’d believe that a premade house would be fine as once again it’d just be downloaded in CAS and then started or do you mean one of the already housed families in the world? If the latter then I don’t think they’d work as that requires going into the game with a save already created and that won’t open. Not even to get to the manage worlds section.
I wasn’t aware that I could rename my mods folder so I haven’t tried that, will the game still recognise it?
I also downloaded some new CC once this problem started and tried to play with just that new cc and the game still wouldn’t load, script mods seem to be fine though which is puzzling.
