Since 2 or 3 server crashes ago, I have an oddity in my base:
During one of the server crashes, I was roasting meat over a campfire. After the crash, the campfire was still there, but no longer burned. I relit it, and finished roasting my meats. The fire burnt out.
However, when the server comes back on, and I log in, I find that the campfire has respawned. I can light it again and roast on it.
Also, I stuck a torch in a torchholder and lit it, and after the server came back online, the torch was gone from it
