I encounter an issue when symmetrizing the Edit bones through the operator
bpy.ops.armature.symmetrize(direction='POSITIVE_X')
The operator copies the widgets from the left to the right side (e.g. the bone nose.R.001 has the widget WGT-rig_nose.L.002 instead of WGT-rig_nose.R.002 after the operation).
The shapes are missing completely after saving and reloading once. Is there a way to keep the custom shapes without using a custom script? Thank you very much!
