Alright, I was playing on my singleplayer world, and I decided to give my small house a major overhaul. When I was finished, I went downstairs to my enchantment room, and it was destroyed. I didn't know what caused it, since it never happened before. I quickly repaired it and went back to my business. Later, I come down again, and I see that it's been destroyed again. This time, I thought that it had burned down somehow, since the room was made out of wood. There's some lava under glass in the floor for decoration purposes, but it was surrounded by stone, and like I said before,this hasn't happened until now. Any ideas on what's going on? If so, please tell me.
