not sure if this is valheim server or my server manager yet but since the last server update, every server i start wipes itself on start-up :/ Explored areas stay explored on the map, character is fine but all buildings, ships etc and their contents are removed :/

The map seems to be getting rebuilt on startup (same extended startup as a new map) and on shutdown i end up with a db file massively smaller than the .old version so no filename config issues, just something triggering the wipe.

any ideas, leads, suggestions? all vanilla worlds that were working fine yesterday :(
