Using scrap for currency

Using scrap for currency doesn't seem to work keeps saying Insufficient funds, I found when using scrap in shop controller It counts a stack of scrap as 1 currency.

also how do I add or find "SpecialId":  when adding manually? for custom plugins like 

  "BlackMarket": [
    {
      "ItemId": 1397052267,
      "Shortname": "supply.signal",
      "DisplayName": "Heli Signal (Easy)",
      "SkinId": 2920175997,
      "InUse": true,
      "Amount": 1,
      "Cost": 0,
      "Cooldown": 0.0,
      "SpecialId": 97927638
    }
  ]
}

Changed Status from Pending to Closed

Changed Fixed In to 1.0.6
