drupal zen theme using sass - sub folder dont get regenerated
compass watch should only need to be run from your subtheme folder.  Files in the components and layout folders should use partials (files beginning with underscore).  Then you have to make sure to use @import "components/fixed"; inside your styles.scss for each partial you want to include.

When compass compiles the styles.scss file, the partials that you have @import's for will be automatically included in style.css
