When I attempt to add a .wav to a NPC as dialog the CK wont save the file or the lipsync file, In the box above save I can see the destination of the file data/sound/voices/.esp/voicetype/.wav

However when I hit save and I check in that directory it is not there at all. Also if I double click the destination to try to get the file to playback I eather get nothing or a notification saying that the sound was unable to be played

The .wav files are in the correct format and I even tried using a .wav file from an old mod that works ingame and it still won't save the file

The 'Preview' button plays the sound fine.
