I was playing in my Minecraft Survival world and I went outside to defeat a zombie and I was heading back to my house and everything went pitch black and all I could see was rain and clouds. Then everything turned purple like a bright purple. Then the diamond sword I was carrying turned into bone meal; enchanted bone meal. (It was still a diamond sword in my inventory)
I have no idea if this is already a glitch or a bug but now I can figure out how to turn my sword back.
