Not been on in about a week, so decided to go on tonight. Logged on to the server (official pve 3063) and EVERYTHING has gone bar a torch. I have spent along time building and collecting and now I have nothing left. This is absolutely stupid.

Steps on how to reproduce issue:

it de-spawns after 144hrs so if your not online to update the timer (must be next to the building) then it will decay and disappear when it decay state people can destroy the structure because it has been vacant for so long
