Additional context

Proposed fix:
Seems to be leaving None in the object list after removing 'Atmosphere' and 'Atmosphere Fine' in global_flat_shading(). See https://docs.blender.org/api/current/info_gotcha.html

Adding bpy.context.view_layer.update() to the end of first for loop in global_shading() seems to fix it. I'll put in a PR.
