The game failed to save error( sims 4)

Hi @kdb1601

Are you using any custom content or mods in your game ?

a lot of custom content/mods is outdated and needs updating.

Try removing everything and see if it then loads.

If it does, narrow down which one it could be,

Here's a list: http://forums.thesims.com/en_US/discussion/941998/broken-updated-mods-seasons-june-2018-patch

If you are not using any, do you have the same issues on multiple saves or just a certain one ?
