Collection showing up empty

Will try to reproduce asap.

Now my only issue is modifying the rss template.

Looks like this example is missing in our docs :thinking: You can disable rss for a collection and define a custom route.

This should work (use the template name you want to choose):

routes:
  /posts/rss/:
    template: posts-rss
    content_type: xml

collections:
  /posts/:
    permalink: /posts/{slug}/
    rss: false
    template:
      - index
