I'm running a BDS in the cloud. I updated yesterday from 1.40.20 to 1.14.30. When I signed in after the update (from Windows 10), everything worked perfectly, but my friend was not so lucky. When he signed in from PS4, the game had cleared his inventory and respawned him at the world spawn point.

I have a complete backup of the world/ folder from before I upgraded and can upload a copy to you for debugging if you are interested in attempting to reproduce the error.
