Re: SIMS4 data disappearing
@p_sty1 What shortcut name did you change?
Clearing the EA App's cache should never touch any Sims 4 user data (saves, mods, etc.). The App cache data is stored in entirely different locations, which cannot be changed, and the process to clear the cache is automated and only looks in the relevant locations. It's much more likely that this is a coincidence, that something else happened at the same time to delete or move the user data.
If you were told to move the Sims 4 folder in Documents > Electronic Arts, that would remove (but not delete) all user data, which is the point of the clean folder test. Please let me know if you've done this, or messed with the contents of Electronic Arts in any way.
Please also let me know where you've installed Sims 4 itself. You can see it in the EA App under Sims 4 > Manage > View properties.
