Relogged today and dicovered my Satchel had reverted from Hardened back to basic model. All contents in extra storage row also lost??? Have no idea what caused this or can't find any reports of this happening before. Reported in case this repeats for other players.

unable to replicate

Actually it appears my entire player inventory has done a 'rollback'! Everything else on my single player world is up to date as last saved? The rollback has obviously returned to prior crafting the basic to hardened satchel which also explains why i encountered a lot of finished quest notifications i had already done upon logging on.
Very strange but someone may know why this has happened. My character has been rolled back basically.
