Hi,
Just to say that I also get a similar bug, except that it only seems to happens to folders that were saved on my desktop.
From what I can see it restores the project folder and then generates a "index" folder.
I've attached an some example images, you can see the restored folder only has "123456_abcdef_bng_index" inside, in turn that has 3 folders, all of which are empty.
This happens every time i turn on my computer now, this never used to happen.
