Why Hugo v0.35 keeps ignoring my subfolder

Hi,

I started a project long time ago, so probably a lot has changed.
Project is placed at https://github.com/mblataric/logonweb/tree/develop
I have Hugo v0.35 on macOS installed with brew.

I added new folder to my project at content/programska-rjesenja/financijsko-poslovanje and everyhing in that folder is not generated in public folder (nor it is accessible in hugo server -D).

I tried various combinations of _index.md, setting front matter in different ways, but whatever I do, hugo never process files under financijsko-poslovanje.

I am not getting any errors on build, only warn about language features which I am not using.
This is my current output log:

It says 16 pages, but on disk there are no pages from financijsko-poslovanje.

Thanks,

Hm, getting back to this after couple of hours and content is now being generated.

Are there some caching involved that needs to be reseted when new content is added?
