I had a big base set up with barrels and tents since a couple days after the stable update. Just yesterday, the server my base was set up on died twice in a row and everything I had was gone; trucks, barrels, and tents. The first time it died, I was able to see the V3S I was driving a little far away from where I was driving it when the server died, and along with a barrel I had stashed in the city I was currently in. Then the server died again, and upon rejoining, I did not see the barrel or truck. I ran all the way back to my base, only to find it had disappeared without a trace.
