Small fix for a problem I was having with sourcemaps and gulp-sass/gulp-autoprefixer

gulpfile.js

var gulp         = require("gulp");
var sourcemaps   = require("gulp-sourcemaps");
var sass         = require("gulp-sass");
var autoprefixer = require("gulp-autoprefixer");

gulp.task("sass", function() {
  gulp.src("scss/**/*.scss")
    .pipe(sourcemaps.init())
    .pipe(sass().on("error", sass.logError))
    .pipe(sourcemaps.write())
    .pipe(sourcemaps.init({
      loadMaps: true
    }))
    .pipe(autoprefixer())
    .pipe(sourcemaps.write())
    .pipe(gulp.dest("css"))
});
