Short description of error
This may not necessarily be an error, but it results in Odd if not completely wrong behavior.
- Create a new file.
- Add armature Human Metarig
- Generate Rigyfy Rig.
- Enter Pose Mode
- Grab neck bone, and G Z Upwards, or around.
You'll see arms, breast, clavicles, just assuming weird shapes.
I do not have an older version to test at the moment, but I'm fairly sure that in prior version moving the neck caused stretching of the neck - not all the other bones that go with it. This is an issue specifically for the Breast bones, since they scale badly.
