saving lot in B&B doesn't actually save

Hi :)

I was continuing to work on a build and while building I saved around 3 times. I saved once more when I turned the game off, and when I came back the build looked like it did before I made all the new progress on it. I tried to recover the saves, and nothing has worked. The funny thing is, I can see the progress in the Manage Worlds tab, but actually opening it reverts back to how it looked before hand.

Is there anything I can do to get my build back?
