Ideas
I have this too. This seems to be a growing issue but EA has not left any notice or posting to say that it is being worked on only that they are tracking complaints. Yesterday I tried downloading a random lot demolishing it and then building and then I was able to upload that build to my gallery JadeMonet_1. I figured it I could open up the door/path to the gallery I could trick it to save. Try that and see if it works for you.
I'll give shot...
