Hi @wh33ly - I apologize for the long delay getting this reviewed. We've been moving all resources to a new CI/CD process that takes a fair amount of effort so I've been behind in my reviews.

I'm also not certain why the tests are failing as it does not look like anything you've done. I'll close/open the PR to kick the AppVeyor again.
