Files disappearing from redirected folders in Windows 10 (DFS gone crazy)...

This was one of those head scratchers...

Decided to give Windows 10 a spin in business environment. Pretty standard setup - Windows Server 2008R2 domain, Windows 7 clients, users' Desktop, Document and Download folders redirected by Group Policy to a DFS share on a Windows Server 2012. Those redirected folders also have offline mode enabled.

Installed Windows 10 on one DELL machine and logged with a test account. To prevent clutter from previous projects being transferred, on a server created new empty structure for redirected folders.

Initially everything seemed OK - folders got redirected, all group policies applied correctly. Then I noticed something very unusual - whenever I create or copy any file to one of the redirected folders (Desktop, Documents, etc.), it immediately disappeared without any traces! Folders were unaffected.
