Here too:

```js
.pipe(cssFilter)
.pipe($.csso())<% if (includeSass && includeBootstrap) { %>
.pipe($.replace('bower_components/bootstrap-sass-official/vendor/assets/fonts/bootstrap','fonts'))<% } %>
.pipe(cssFilter.restore())
```

It will only replace if both Sass and Bootstrap are selected. LESS Bootstrap works fine because they use relative paths which works with our directory structure.
