Hi,
My GI is disappearing whenever I region render. This has happened to me before in other renderers ...but is this expected behaviour in V-Ray?

When rendering out the GI render element for this same scene, the parts of the GI is missing from the actual render element. This can't be right?

I'm on build 14204, Mac OS X Snow Leopard, Maya 2011 64-bit.
Am I doing something wrong?
Scene attached.
