For what it's worth, I've had problems with different things in Light Wave from v8.0 that haven't been resolved. repeated calls to tech support have only been resolved once by me after getting some more information. It seems if you aren't an important studio they tend to forget about you.
I always have hope that the next version will correct it but I have always been disappointed. I expect the same from Core, just magnified because there will be many more bugs they will need to fix before they get around to the ones you need fixed. I hate to be negative, but I chalk it up to experience.
