@font-face not wrapping when converting scss to css?

Question

Sass

The people, who can tell what's wrong?
I screwed up the galp, when converting scss to css, stubbornly does not want to transfer @font-face. It doesn't show any errors though. If in the first one I change @font-face to something else ... some selector, then everything transfers and at the same time all other @font-faces also transfer normally. As soon as I do back the file is created empty. I made a commit from above, but only after transferring it during conversion, but the fonts themselves are not. What can be wrong?

Thanks to all. The issue has been resolved. It turned out to be the cssNano plugin for Gulp. I took it down and put another one to minimize the CSS code and everything began to work as it should)
