SourceMap generates wrong paths

[hashworks]

Example setup with grunt-sass: https://moonbase.hashworks.net/grunt-sass-issue-241.tar

Gruntfile.js
index.html
package.json
css
├── screen.css
└── screen.css.map
sass
└── screen.scss

screen.css.map:

{
        "version": 3,
        "file": "screen.css",
        "sources": [
                "../screen.scss"
        ],
        "sourcesContent": [],
        "mappings": "AAAA;EAIC,AAAkB;EAHnB,AAAM;IACJ,AAAkB",
        "names": []
}

Should be ../sass/screen.scss.

Thanks for the report @hashworks. Could you please created a small GitHub repo with a minimal work example reproducing this issue. This will ensure there are no other external factors.
Also our experience the process of creating these test repos in itself surfaces the problem.

Hi, sry for the dead link.

I reproduced my case with grunt-sass v0.18.1, however it seems to be fixed with grunt-sass v1.1.0-beta (which includes node-sass v3.0 and libsass v3.2.0).
