Grafic layer disappears when using IK Bones

[juliak14622937]

I've converted a drawing into a grafic-symbol. Go into the symbol and draw a bone onto my layer. the drawn  layer disappears and an armature (Skelett)layer was created. Now I have no chance to make any corrections on my drawing. How can I fix that, so that drawing bones creates another layer ontop without deleting the grafic?

Not sure there is a way to do this automatically, but you could try making a copy of the artwork layer before adding your rig. Then at least you have a backup.

just duplicate the layer.
