Unable to @include foundation-forms(); on fresh install

[rbrlortie]

On a fresh Nwayo install, I'm attempting to uncomment the following line // @include foundation-forms(); in \components\foundation\styles\_base.scss.

This outputs the following error:

Error in plugin "sass"

This is caused by the default values being em in \components\foundation\styles\config\_design.scss under the // 20. Forms section.

Changing those values to use the ones on https://foundation.zurb.com/sites/docs/forms.html#sass-reference fixes the problem (or simply commenting them and allowing Foundation to use it's default would also do the job).
