I added Redstone in an anvil (I know I am not suppose to, I just wanted to see what would happen) The game crashed. Redstone can not go in my inventory any more. I can gather it from the ground, but no redstone. If I go to a anvil redstone is there in my inventory, but I do not have it. There are other things that I can see in an anvil that are not in my inventory. Maybe that is where everything that I craft and then go to use, but can not find is going. I thought I was just losing my mind.
