sass bug in responsive.scss

The mixin for border-radius on line 1210 is bugging out.

wrong number of arguments (4 for 1) for `border-radius'
on line 1210 of source/assets/stylesheets/sass/_responsive.scss
@include border-radius(0, 0, 3px, 3px)

What do you recommend I patch?

Line 1210:

@include border-radius(0, 0, 3px, 3px)

Should become:

@include border-radius(0 0 3px 3px)

Correct?

Think's for your patch gothassos !

It work for me to on version 4.2 (files sass/responsive.scss).
I also need to add this two lines at the top of the file :
@import "varibales.scss";
@import "mixins.scss";
