Hugo sometimes does not recognize pages

Both branches and leaves sometimes render, sometimes present an empty page (empty pre tag), sometimes throw a 404. When I force a safe, the pages appear, only to disappear after a server restart.

I am a bit clueless, why this occurs.

you have an on content root. Hugo will treat the whole content folder as leaf bundle, means all the other markdown files treated as leaf bundle page resources.

rename content/ to content/

Holy Moly! I know about bundles and still sometimes such basic things evade my perception. I looked everywhere else a 100 times, or so as I was expection something along the lines.

Still, I wonder why pages did show up, when you saved/touched them.
