es solo 1 comando, ese unico comando genera todos los necesarios

lo de multiples comandos en un solo comando es algo ya conocido desde la 1.7, yo cree la cajita de bedrock, use un filtro para hacer el comando, y luego lo edite a mano para añadir un par de comandos para el scoreboard etc

pd: lo de dar scoreboards es que desde que pusieron que con /scoreboard players se pueda poner a cosas con nbt especificas, basicamente es como si hubiesen puesto un selector para nbt tags "@e[nbt = ]" ya que simplemente creas un objetivo y le das score a el que cumpla la nbt tag, asi que los comandos hacen que "@e[nbt=id:minecraft:log]" si tienen madera encima, seblock aire encima, si tienen madera debajo, setblock madera debajo, etc etc

eso no es un error, esta hecho a posta, para poder parar el reloj mas facilmente, no es necesario quitarlo, eso hace que solo si hay piedra se ponga redstone, y solo si hay redstone se ponga piedra, asi que si lo rompes (aire) no se pondra de nuevo, que es lo que les pasa a los normales de solo fill sin replace, ademas esto permite que active o desactive una parte que no esta incluida en la version posteada, pero eran 3 comandos que permitian que los saplings se plantaran solos de nuevo, y si quitava el bloque de redstone de ahi, se desactivava
