So…kind of awkward. I deployed the same repo on Vercel (formerly ZEIT) to see if anything weird happens too, and it turns out…nothing happened! You can go see the site to verify: https://dowww.now.sh
Opening one of the inner pages directly (for instance: https://dowww.now.sh/1.1/4-Advanced/4-2-LxRunOffline.html) shows no errors inside the console, and I can also click on the sidebar to navigate! Weird!
I was wondering if there’s a way to force-delete all my build cache and do a 100% complete rebuild of my site on Netlify without me deleting and re-importing my site? (You guys have awesome load time in China and I don’t want to make the switch to be honest.) Thanks for all the help and for hosting all (literally all! 
) my websites!
