It did! Two of the visualizations error 'Could not locate that index-pattern-field' for useragent.device.raw and useragenent.os.raw but I can figure that out, I think.
Something like that could be super helpful. I've seen a few very slick looking dashboards/ visualizations with no idea how to duplicate the work, except pick through them step by step. That's great for learning, but it's hell on deadlines.
