Launcher show latest versions as unavailable

So I’m playing on 10614 for the moment, waiting for at least item-breaking bugs of NC update to be fixed, but I was expecting to be able to update to latest when they are fixed. Instead, launcher shows latest available build is 10667 (6 days ago), and all higher numbers are shown in the list as unavailable. Why?
I can update manually, of course, but maybe launcher knows something I don’t? Like I have to update to 10667 first (e: then start the game so it processes whatever it have to process), and then to the next latest available, otherwise my save will definitely be broken?

You need to update the launcher itself, then you will be able to download the newer builds.
