I have the following problem with my Rigify rig. When i rotate the headbone in pose mode the mesh does not rotate with the bone anymore. I can still move the bone and the head deforms, but it does not rotate. If i rotate the neck bone, the head rotates with it just fine. It still works on an older version of my model so there must be something messed up.
What i tried: Checking the weight paint. Messing around with Neck follow and Head follow. Looking around for possible differences between the old and the new model.
If someone has any idea what could cause this, please let me now.
