InsufficientFunds error on contract deploy (TestNet)

[EdgeDLT]

Attempted to deploy a contract on the RC1 TestNet via one of the seed RPC nodes on the DevTracker. Results in an InsufficientFunds message, though the wallet has been loaded with 500 GAS:

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": {
    "balance": [
      {
        "assethash": "0xd2a4cff31913016155e38e474a2c06d08be276cf",
        "amount": "50000000000",
        "lastupdatedblock": 13676
      }
    ],
    "address": "NVBmGQMFYXuiNqYSSVFgZPu1LDVRERt7Dx"
  }
}

Could be that it hasn't updated the right hash for the GasToken contract on the RC1 chain?
