Server Error uploading to gallery/library

I've been having the same issue for about 2 weeks.

I started having glitches in my most used save and I've been worried that the corrupted save bug has hit me. So I've been trying to save all my lots and families to my library so I can migrate them, but I keep getting the message "Server error. We could not process this gallery request. Please try again later."

At first, I could only save rooms, but today, NOTHING works.

I don't use mods or custom content.

This is so frustrating. My game is unusable. I've spent so much money on this game that it would be nice to get this fixed or get some sort of acknowledgment that they're working on it.
