If you're sure this default network represents your development environment, you can ignore processing of the default network by passing `true` as the second argument to this function. However, if you think this network represents artifacts you'd like to keep (i.e., addresses deployed to the main network), you'll need to edit your .sol.js file yourself and change the default network id to be the id of your desired network.
