"Pack All Into .blend" and then "Unpack All Into Files" sounds issue

In Korman 0.16:
For example, if my sound files are in my "sfx" folder, and I do "`Pack All Into .blend`", move the .blend file to another location, do "`Unpack All Into Files > Use files in current directory (create when necessary)`", a "sounds" folder is created with my sounds files inside, but blender still use the sound files from my "sfx" folder.
