I've noticed little fires popping up here and there at my underground base in the Wild. I was told sometimes this can happen on obsidian if directly on top of lava. So, I fixed that particular issue just to be safe.But, I went to my animal pens today and nearly all the fences were missing around my sheep pen, and all but one of my sheep were gone. Several of the wood blocks under the fences were gone too. However, all my other animals and pens are fine.So, I've either been griefed in an odd way (nothing else was ruined or taken) or a fire may have occurred. Strange thing is, there is no obsidian or lava directly. underneath these pens.
