Hello Minecraft I don't know this bug or no But I contacted support to want to know. They said this is a problem and write your problem here. Well, why is it that when I hit a villager, the prices do not rise, and when I kill a villager, the price does not rise iron Golem By attacking me Is this a bug or is this a feature that was deleted from the game?
