Quote - The bug is still not resolved.  Will probably be fixed after the holidays. 

The problem is with ecosystems and layered materials.  If I make a three layer material and in the middle material, I added an ecosystem, the ecosystem goes all over, not just sticking to the middle material. 

Thank you, Peggy.  Your explanation is much more to the point and well said in fewer words.

So - OK on the bug still being there.  But at least they are aware of it and apparently still working on it.
