So I was looking at the Lock wiki wilderness guide, and at the items, it said a wooden door is lockable. I place a lock sign, but it doesn't register. I put a lock sign behind it, doesn't register. I move the door, and place the sign on the side, doesn't register. I was scratching my head and thought maybe there was a mistake and only iron doors open. I did the same sequence with iron doors but it STILL doesn't lock.Can I have some help here?Also, there also could be a suggestion here. Could Iron Doors be added to be lockable. If wooden doors are lockable, how about iron doors, so they cannot be destroyed, needs redstone, and its locked.
