Hello. Is this a bug? It’s easily reproducable. Description would be: Blender release 2.79; When deleting ear bones from Rigify Human metarig to generate actual rig does not work.
Add Armature, Human (Meta-Rig). In editmode, delete ear-bones. In objectmode, hit “Generate Rig” button produces stacktrace, where the final line is “KeyError: ‘bpy_prop_collection[key]: key “ORG-ear.L” not found’”
I have always been able to delete fingerbones if needed. And that works also now. I could just leave the ear bones there, but I think they are non essential, so they should be able to be removed.
I read today they are going to make a second release 2.79-a, so this could be fixed there.
