Noticed something today. The jiggle deformer does not seem to work like the other deformers, in that it only seems to work if its a direct child of the object you need it to deform. Most deformers work if they are in the same level hierarchy as the deformed object. Is this a bug or just the nature of how the deformer needs to be set up?
Attached is a file and 2 screenshots. A is set up with deformers and object as children of a null. B is set up with deformers a child of the object. On my end, jiggle only works in example B.
