All constructions inside all castles are gone

All constructions (apart from heart, blood altar, storage and thrones) are gone from all my and my friends castles. This includes all items that was included in the construction.

Since this happened (17:th of June), the server seem to have lost all players (0 logged in average).

After suiciding, it appears my throne has been relocated to a neighbours castle. When spawning on it, it appears all constructions are somehow stacked in height, on the same coordinate.

Please assist. This is the first playthrough of the game and this kind of abuse drastically impacts the player experience - I won't continue playing the game if not handled.
