saving and uploading to Gallery broken since introduction of Marketplace

It's a 50/50 chance that ANYTHING gets saved to my personal profile when saving builds/rooms/Sims, as well as when uploading to the Gallery. There are no popups alerting me that anything is wrong or that I'm unable to save/upload. The game shows that saving/uploading goes through, only for me to discover later on that it never did and that my work is gone. Also, there's another bug where it appears most of my saved builds/rooms/Sims on my personal file aren't there, but at other times when I log on to play, they are there. That said, it's wasted time if my efforts can't be saved.

And no, I don't have mods on.
