I read my was just a question because I saw a daily development and I felt weird that it could not be used

Not weird at all - it is to be expected that there will be days when some of these bleeding edge test builds don't work as reliably as we'd like, particularly when new features are integrated that contain new bugs that are (usually) quickly fixed.

Obviously everyone does their best to minimise the breaks but sometimes it can't be helped.

If you want stability then stick with release builds.
