router-scroll location type breaks non-root routes in development

Create new ember-cli app:

1. ember new router-scroll-test
2. cd router-scroll-test
3. Remove ember-welcome-page addon
4. ember generate route nested
5. Add content to app/templates/nested.hbs
6. ember serve
7. Visit localhost:4200/nested (content loads fine)

Introduce ember-router-scroll:

1. ember install ember-router-scroll
2. Follow README setup (import mixin into router.js; set locationType: 'router-scroll')
3. Restart development server with ember serve
4. Visit localhost:4200/nested

It seems that something in the 'router-scroll' locationType is breaking the development express server’s ability to load the app directly into a non-root route. This is especially frustrating when livereload is constantly refreshing the page during development (triggering this error each time).

https://github.com/dollarshaveclub/ember-router-scroll/pull/28 has the instructions in the readme. I’m having a hard time explaining how to concisely explain why that config is needed, so I just linked to the issue.

Hi @kpfefferle. Thanks for letting us know. I am able to reproduce it. @bcardarella is working with the ember team to get the router-scroll location API stuff into mainline ember, so I think after that, it might resolve itself, hopefully.
