The puppet is running well for me - I can get it up to around 45fps on my 2016 Macbook Pro. The only reason I would imagine it's running at 6fps is due to either a) lower hardware specs, or b) other open programs reducing memory usage.
I didn't notice the disappearing eyelashes but I do see they're in the same group as the blink cycle. So if they're disappearing I would guess it's tied to something with blinks, since blink tagged stuff hides everything else at its same group level.
