I created a character and animated it using bones and shape-key drivers.
To handle several scenes, I added a new scene using "Link Object Data" allowing me to manipulate the position of my character and the position of bones.
Everything works fine, except the shape key drivers. The driver still references the bones from the old scene, updating the reference manually works.
Attached an example with 2 scenes, in the second scene (duplicated using "Link ObData"), the shape key driver doesn't work anymore.
