Hi I noticed this issue. I guess it is easy for to fix.
Windows 10 GTX 980
Short description of error
eyes and nose bones are parented to ear bones
Exact steps for others to reproduce the error
- Add Armature> Animals> Horse
- Pose mode
- select earL and move
- Eyes and nose bones move with the earL bone too because they are parented to the earL bone.
- When you animate ears eyes and nose bones will move too.
