I have a few kits that only contain blueprints. After using the conversion command, the kits converted but contain only generic/default blueprint icon and they cannot be learned.

Kits old version

       {
          "itemid": -996920608,
          "container": "main",
          "amount": 1,
          "skinid": 0,
          "weapon": false,
          "blueprintTarget": -798293154,
          "mods": []
        },​

Result in new version after running convert command

        {
          "Shortname": "blueprintbase",
          "Skin": 0,
          "Amount": 1,
          "Condition": 0.0,
          "MaxCondition": 0.0,
          "Ammo": 0,
          "Ammotype": null,
          "Position": 0,
          "Frequency": 0,
          "Instance": {
            "DataInt": 0,
            "BlueprintTarget": 0,
            "BlueprintAmount": 0,
            "SubEntityNetID": 0
          },
          "Contents": null
        },​
