After I've blown up a whole bunch of random mobs in one hole, I found a strange figure of light. It looks like I've placed an Ender chest or a glowstone block, or a torch, or any type of lighting source, but I didn't. There wasn't even any lighting source around. And near that I found fire. I thought putting out the fire will take out the body of light, but it didn't. I've restarted the world, didn't work. I've restarted Minecraft, didn't work.Never mind, the light went out. But what would cause this? And why when I dug down the sides were changing different shades of black as if it was fire?
