Здравейте, получвам 88/100 и не мога да разбера къде точно греша, някой може ли да ми помогне ?

Благодаря :)

задача : https://judge.softuni.org/Contests/Practice/Index/2028#2

код:

function solve(arr) {
    let items = arr.shift().split(', ');
    let command = arr.shift();
    let actions = {Collect : collect, Drop:object => items = items.filter(x => x !== object), 
          "Combine Items" : combineItems, Renew : renew
                  }     
    function collect(object){
      if(!items.includes(object)) items.push(object)
    }
    
    function combineItems(object){
      let [oldItem, newItem] = object.split(':');
      let index = items.findIndex(x => x === oldItem)
        if(index >= 0){
                    items.splice(index + 1, 0, newItem);
                }
    }
    function renew(object){
            items = items.filter(x => x !== object);
            items.push(object);
    }
    while (command !== 'Craft!') {
        let [action, object] = command.split(' - ');
        command = arr.shift()
        actions[action](object)
            } 
    console.log(items.join(", ")) 
  }
