It appears this is not a pc specific issue.TheSimsDirect I am a mac user, and u can see in this thread there are console players with this issue as well. As I mentioned before, it’s not internet connection or simply gallery issue also, as saving to my private library shows the same error. The update broke something and it should be fixed as soon as possible.
I have the same issue. Saving your builds to your own library shouldn't even be a problem. My game duplicated my save game onto another saved game erasing everything I use for my YouTube. And rather than being able to re-download my saved lots I had to re-build houses and cheat my sims skills back. I've been doing that all weekend rather than just streaming and playing. Not being able to save your builds is crazy.
