My quest giver has speech and lipsync files, he works fine on my rig. So i packed up the .bsa with all the necessary files including the SEQ and upload to Steam. On my gf's rig the quest starts nicely and we can hear the audio, but the lips just aren't moving.

Is this a bug since patch 1.9....I have no idea what's gone wrong as my previous uploads all worked fine. Any help would be appreciated.

I used archive.exe to make the .bsa file, with Data as the root etc, all correct boxes ticked. I'm stumped !
