Server Error whenever I'm upload to my personal gallery

A few days ago, I tried to save a very elaborate build to the gallery to place it in a different saves file, from my one specifically for building. I could not upload it at all in five tries, and the last time that it did upload when placed only placed terrain paint. When I went to try again today, I tried uploading and it did, but it says "Server error. We could not process this Gallery request. Please try again later." Even though the lot turns up in both uploads and my personal gallery, when placed, it places nothing. I have no mods or cc in my game and have no idea what's wrong. It may have started after this latest patch, but otherwise, I have no idea.

Is there anyone else who has this problem?
