Well I can go on a rant on how www was never a thing defined in any web standards besides marketing companies who thought it was hip and cool to advertise and brainwash everyone into thinking it was how the internet worked. Chrome recently took up the fight to automatically suppress/hide www in urls.
Or I can say I fixed it after breaking it unknowingly last night 
www now has a permanent 301 redirect to the non www. And fixed the underlaying issue with relative file paths after the addition of integrity and cors.
It’s easier next time for anyone with website issues to report it in the github repo (still there) as we get notifications immediately.
