Repro for build issue with content in subdirectories

[tleef]

When in dev, everything works fine however, when you build this example, content that is nested in subdirectories will not be found. The reason being that the files associated with this content are missing in the dist folder that is generated.

The content folder looks like this

content/
-pages/
--about.md
-posts/
--tech/
---first-post.md
---third-post.md
---fifth-post.md
--photography/
---second-post.md
---fourth-post.md

And the dist folder that is generated should look like this but the files/folders that I've marked are missing

dist/
-index.html
-about/
--index.html
-tech/
--index.html
--first-post/ **missing**
---index.html **missing**
--third-post/ **missing**
---index.html **missing**
--fifth-post/ **missing**
---index.html **missing**
-photography/
--index.html
--second-post/ **missing**
---index.html **missing**
--fourth-post/ **missing**
---index.html **missing**
-phenomic/
--pages/
---item/
----about.json
--posts/
---by-default/
----(more files and folders here, all are correct, not relevant)
---tech/
----by-default/
-----(more files and folders here, all are correct, not relevant)
----item/ **missing**
-----first-post.json **missing**
-----third-post.json **missing**
-----fifth-post.json **missing**
---photography/
----by-default/
-----(more files and folders here, all are correct, not relevant)
----item/ **missing**
-----second-post.json **missing**
-----fourth-post.json **missing**

I hope this helps, let me know if you have trouble reproducing
