Me and a friend have been playing the same server since we got it, were at around 5-600 days in game time. Lots built up. Literally everything there. Its all gone, the maps still explored, the players spawn in at the original starting rocks. My friend is unsure if they want to keep playing now at all or just quit. Game breaking bug, community destroying bug, give us an official response or your game is over today.

Edit: steam cloud save, the server has also been reset and lists it as like day 4. All previous posts about lost content related to local saves do not apply.
