702 Zenview won't save, endless loading screen

While playing with sims in 702 Zenview in City Living, I'm unable to save. I'm not having problems in any other City Living apartment or household, just Zenview. If I select to save, there will only be an endless saving loading screen. The same happens if I'm playing in 702 Zenview and then select "Manage Worlds" without saving. I've had to force quit every time. Is anyone else having this problem? Is there a solution? I don't use CC and I've tried repairing the game through Origin. 

Thank you for your help!
