--watch not working with 3.4.2

[Sechgulo]

Today I decided to get rid of all the prefixes in one of my projects and installed Bourbon(which uped my sass version to 3.4.2. Right after, the exact same watch command stopped working:

>>> Sass is watching for changes. Press Ctrl-C to stop.
      write styles/style.css
      write styles/style.css.map

When I try to save the scss file nothing happens..
Have tried with absolute path, changing paths, reinstalled sass and bourbon but nothing changes.

Once tried to do a non watch command, just a normal override and got "Errno::EACCESS…permission denied". Restared the computer and cant recreate that error.

Reinstalled sass but with version 3.4.1 and it now works again
