In general, with 4000 working examples working via multiple stylesheet conversions, your last three items are rarely needed.  If they are needed, then the fault in question must be completely isolated first.

Hmmm "dropped off a ProtoInstance" ?  Note that a ProtoInstance needs to declare its containerField value, otherwise the (parent node -- child ProtoInstance) relationship is not defined.

Checking your original .x3d XML models in X3D Validator is a good way to isolate such errors in content.

Good luck with further sleuthing and problem isolation.

all the best, Don
