Can you resolve the merge conflicts and then I'll approve?

[
      "DiscountedFee",
      {
        "nth": 48,
        "isVLEncoded": false,
        "isSerialized": true,
        "isSigningField": true,
        "type": "UInt32"
      }
    ],

Doesn't exist anymore right? So that needs to be removed.

@dangell7 No it still exists, it needs to be changed to 6.
