I can't figure out what's going wrong exactly. I can't even get your project to run as the install fails because of node-sass and node-gyp.
My guess is since your links and URLs work at least once then the link resolver and link components are working, but something in your node modules is interfering.
The best way to trouble shoot is to try and disable module by module starting with the CSS modules (which is my guess where the issue is coming from).
