in my multi-language grav project the routes defined in site.yaml are ignored or not working.
therefore I created the following routes block in site.yaml as described in http://learn.getgrav.org/content/routing
routes: /something/en-US/(.*): '/something/$1'
I tried to configue it via admin plugin and without regex but nothing worked.
When I configure the default route in the page itself, it works perfectly.
