Short description of error
"Horse (Meta-Rig)" has a bone that was incorrectly parented. Specifically, the "ear.L" bone has been parented from "eye.L/R" and "nose.L/R". It is unnecessary.
This bug was confirmed and fixed in T54100: Rigify: Animal Horse rig parenting issue a year ago, and worked in Blender 2.91.2. But in a recent version (2.93.0), the bug has recurred.
Exact steps for others to reproduce the error
- Open a new Blend file
- "Shift+A > Armature > Animals > Horse (Meta-Rig)"
- Enter Pose mode
- Select "ear.L" bone and rotate -> "eye.L/R" and "nose.L/R" rotate too
