More feedback 10.2.2 :
This involves the new single binary file option.
When editing a soundfile in a loaded single-file voicepack, you first have to reset that soundfile to default, then load the new sound (and then re-publish). Otherwise it would just keep playing whatever the sound originally was.
If a user would want to change a couple sounds in a published single-file voicepack, it wouldn't be intuitive for them to do so.
Maybe a tooltip that points out to press "default" first on any sound you want to change?
If that's a serious offer, I think we can produce one for you guys! Well not me specifically, my photoshop skills wouldn't be even able to put a big red X on say the juggernaut achievement image...
