Assuming you can make a support ticket (which is the new bug tracked at Daz), I would drop one in for Technical Support, and start with 8.5 Carrara Beta in the title.

I just made one for another issue, failing to import a duf, and Daz_Spooky hasked me to put it there.  Supposedly they are on build 243 or something...heading for release.

...best to get it in now, if its repeatable.
