All items disappearing from workbench/blacksmith

Game mode: [Singleplayer]
Problem: [Bug]
Region: [EU official server #1128]

So earlier today while playing on an official EU conan server one of the players was very confused as he had lost all items in his workbench overnight while his base was still intact.

Just now I put in some steel in my blacksmith and started crafting reinforcements, after organizing some chests for a bit I went to check on my blacksmith and noticed all items had disappeared, but the thrall was still in it.

The blacksmith is behind 3 layers of walls so no one could have accessed it from outside, no one else from my clan was online so they could not have taken it either, besides I would have heard the doors open.

Steps on how to reproduce issue:

  1. Place items in blacksmith
  2. play the game
  3. watch items disappear in the blacksmith
