Unable to get motion blur on cached surface with Ornatrix...

[Njen]

I'm not sure if this is an Ornatrix or Corona issue, nevertheless I'm posting the same problem on both forums.

I have an object with a Point Cache modifier that I am scattering Ornatrix hair over to act as fuzz. The object that is point cached seems to motion blur fine, however, as you can see in the image (alpha channel), the Ornatrix hair fuzz is not motion blurred. I've tried increasing all of the motion blur related settings, but nothing changes.
