2.8.3 ruined child-theme

I have a child theme with nothing in it but for some reason it is not picking up on the style.css.

I’m assuming this has to do with the following change (from changelog):

Even faster loading, thanks to minified and concatenated styles and scripts.

A child theme has nothing in it, just the standard:

@import url(“../decode/style.css”);

Everything works but it seems like the style.css isn’t working at all as nothing looks proper. Any idea how to fix this?
