Thanks, nruddock!

What is Double Feeding?

I deleted all of the Magents, but they were'nt the cause.

Apparently The Wymmaster Dynamic Deformer's Remotes are'nt being welcomed into P7; when I removed them I got the image above.

Any ideas? 

As far as I know Poser ca'nt create these.  I wonder where Wymmaster got them, and why he went with remotes, over magnets.
