Vegas 17 + PI + event reference doesn't reference

I suspect this is a Vegas bug, though it could be a limitation in OFX too. I’m reporting it here because you guys are more responsive than and probably have a tighter relationship with Magix than their users do.

o Create a solid color media event. I used black but it shouldn’t matter.
o Apply a Particle Illusion effect. Again, shouldn’t matter which. I’m using some customized fx and can supply the project if you can’t repro.
o Duplicate the event and when asked, create a reference instead of a copy.
o Go back into PI and change the fx in some obvious way.

You should see that the event with the modified fx shows your change but the reference doesn’t. It looks like at some level, either the fx is being copied or the internal PI data is, rather being a reference to the original.
