Placticity and adhesion of layers to one another

[Animation-Brooklyn]

When I draw a pair of lips on a layer that is above the body drawing of my segmented worm character the lips that are above the drawing move and deform with the bones and other drawings that are on the various layers which comprise the character. (i have all the vector layers of the worm character within a rigged bone layer)

However once I draw additional mouth visemes and place them all within a "switched layer", the new switched grouping no longer tracks with the bone skeleton - i must link the entire switched layer to a bone to get it to move but now the lips do NOT deform with the other parts of teh animation like they did when they were not in a switched layer. And it looks like it's a cut out just pasted on because it is not deforming along with the other surfaces of this worm like character.

(also the mouth layer curiously tracks along with the bones properly even though they have not been linked to a bone.)

The bone sytrength tool does nothing to help the lips within the switched layer more naturally distort with the surrounding drawing. However as soon as i move teh lips out of the switched layer they immediatly cling to teh rest of teh drawing and move along with it.

I am sure this is something I am overlooking.

Thank you in advance for your time.

Bones only influence layers directly inside the bone layer - not in a layer inside another layer.
You can create bones in the switch layer so they will influence whatever you put inside it. However, the combination of switch and bone animation can be tricky, that's why most people use different mouth positions inside a switch layer for the deformation part, and the overall bone only to place the mouth on the face.
