Love the shared world feature even with some of the hiccups I've seen come up from it.  I know currently there's not backup saves other than manually converting the shared world to a standard save, but could this feature be automated?  Basically, the owner/creator of the shared save could enable an automated backup option that updates a standard save alongside the most recent shared world save.  If the players want more granular backups they'd still have to create manual standard copies, but if there was an automated copy of the shared save this would let the owner recreate the shared world when there's issues with the shared world, ie the file corrupts or is missing entirely.  Just a thought.

Would at least be a good workaround for all the inventory deletion bugs people are running in to.
