If you are in this situation:
- Finish your animation
- Then hit “Convert Face setup” from Advanced Skeleton
- Your animation will be messed up
Do the other way around:
- With the original rig, hit “Convert Face setup” first
- Animate and finish your animation.
Some of my rigs were built using older version of Advanced Skeleton, this Convert button might not work… Inbox me if you have this problem (rebuild the face rig will take time though)
