context-slice of 12 can not be determined based on grid-columns

[jenyckee]

When doing
width: susy-span(10);
I get

Error in plugin 'sass'
Message:
    node_modules/susy/sass/susy/_utilities.scss
Error: [susy-normalize-columns] context-slice of `12` can not be determined based on grid-columns `12`.
        on line 43 of node_modules/susy/sass/susy/_utilities.scss
>>   @error '[#{$source}] #{$message}';
   --^

I installed susy with npm and build with gulp. Is this intended behaviour?
