I have a mod that has ten voice acted NPCs and I am having hit and miss lip sync.

1) This https://www.youtube.com/watch?v=-TC_pWStJ2M is the best example I can come up with demonstrating this issue. Right in the beginning when the NPC says, 'certainly a unique name you have there', the lip sync cuts out. This is not the video, I was having this problem with a lot of lines. I found that splitting lines more eliminates the worst of it, but it is still present.

2) Timing issues, I have two NPCs whose lip sync timing is just off. One of these NPCs speaks quite slowly, the other normally. Yet the lip sync is 'off' not only for me but for everyone else who has seen these NPCs in game.

I do lip sync the normal way, put in a line of voiced dialog and press the 'generate lip sync'. Is there any way to make lip sync more precise or is it just a hit and miss thing that nothing us regular non technical inclined folk can do anything about?

The lip sync was broken by update 1.9 and there's nothing we can do about it.

Oh okay, thanks. That is a shame.
