After moving my Documents to iCloud, my Documents folder became empty after 5 days.

Dear mighty all,

I have upgraded to Sierra and (alas), was so silly to move my documents to iCloud. After five days I have NO "Documents" folder available, just a local copy "Documents - KSmirnov" which contains just the last saved document.

When I go to iCloud.com, I see that there are no documents there either.

When I try to restore files there, iCloud says "There was a problem loading restorable files. Please try again later". I have tried first time about 7 hours ago, tried several times since then, to no avail.

No documents on my local drive, no documents in iCloud. Not being able to restore.

Thanks God, I have a Time machine backup from few days ago.

An interesting detail is, that I see that the exactly the amount of disk space that was belonging to my documents is still consumed (about 44 G), yet there are no traces of docs - spotlight does not find any. It sits somewhere, but I cannot find where it is.

Dear all, dear Apple. Any ideas how to fix it?

Just in case - local support suggested I reinstall OS. Not that I want spending my time doing that. I guess there must be an easier way.

Ticket ****, just in case.
