Meteor-scss: All styles are within the document

Hey,
I’ve just released my first React app using meteor-scss. Now I’m having an interesting issue: All styles are within the document and not in a seperate *.css file like on my other Blaze apps. Any idea what’s causing this issue? Is it maybe a problem with import ‘my_component.scss’? My whole head is full of:

<style type="text/css">
</style>
<style type="text/css">
</style>
<style type="text/css">
</style>
<style type="text/css">
</style>
[....]

I don’t think that this should happen in a production environment
