Object frustum culling issue

[Bryce]

Xpost from Programming. I believe this is a Shiva issue and not a code / object config issue:

I forgot to add that the object in question is a group. It contains 1 mesh (parent), and several helper subobjects with box sensors attached. Any ideas what's going on and whether it can be fixed?
