Hello, all! 

I've just gone through the ICC config file, and set prices for components, etc.  Then, I went into the Rust Console and typed "costfile reward" and it gave me a fantastic config file...  But it isn't in the same format as sale_data.json from ServerRewards.  I'm not sure where to put the file from Item Cost Calculator to make it help with ServerRewards.

// sale_data.json format

    "crossbow": {
      "0": {
        "price": 0.0,
        "displayName": "Crossbow",
        "enabled": false
      }
    },

// Item Cost Calculator format

  "crossbow_0": {
    "displayName": "Crossbow",
    "cost": 564,
    "cooldown": 0,
    "shortname": "crossbow",
    "customIcon": null,
    "amount": 1,
    "skinId": 0,
    "isBp": false,
    "category": 1
  },

Should be reward_data..json

*Facepalm*  Found it. Just needed to import the ICC data into the curly brackets under "Items" in the reward_data.json.    Thanks, Arainrr!
