field.css files missing / not getting loaded

Ah, the problem is that the libraries file declares:

> css/components/field.css: {}

and that file does not exist.

The only field.css file in Bartik is at:

> css/classy/components/field.css

And the field.css file that does exist isn't declared.

Ok I have NO idea what's happening, as the git clone of this theme has the files and declares them. AND those haven't been changed since the initial commit.
