Problem ze skryptem na stowniarki i obsydianiarki

Ogólnie mam problem ze skryptem gdyż jak stawiam endstone ktory generuje stone/obsydian to jest wszystko ok tylko gdy niszcze ten endstone wyrzuca mi endstone o nazwie generator i zwykły endstone (ktorego nie chce aby dawało)

tutaj daje skrypt:

on script load:
    register new shaped recipe for end stone named "&6&lGenerator" using emerald, emerald, emerald, emerald, stone, emerald, emerald, emerald, emerald
 
 
command /stoniarka:
    permission: op
    permission message: &cBrak permisji
    trigger:
        add 5 end stone named "&6&lGenerator" to player's inventory
        send "&6Otrzymales generator"
 
 
on place end stone:
    if name of player's tool is "&6&lGenerator":
        add location of block to {generator::*}
        send "&7Postawiles &6&lGenerator &7aby go aktywowac, poloz na niego &6Stone &7lub &6Obsydian"
       
       
       
       
on break end stone:
    loop {generator::*}:
        if loop-value is location of event-block:
            remove location above event-block from {stoniarka::*}
            remove location of event-block from {generator::*}
            if player can hold 1 end stone named "&6&lGenerator":
                add 1 end stone named "&6&lGenerator" to player's inventory
            else:
                drop 1 end stone named "&6&lGenerator"
            stop
               
               
               
on place obsidian or stone:
    loop {generator::*}:
        if loop-value is location under event-block:
            if event-block is stone:
                add location of event-block to {stoniarka::*}
            if event-block is obsidian:
                add location of event-block to {obsydianiarka::*}
            stop
           
           
on break obsidian:
    loop {obsydianiarka::*}:
        if loop-value is location of event-block:
            wait 5 second
            set event-block to obsidian
           
on break stone:
    loop {stoniarka::*}:
        if loop-value is location of event-block:
            wait 2 second
            set block to stone
