Excellent answer. I went through my projects unchecking calculation order and it restored the normal hierarchy for almost all my characters. Unfortunately it didn't help the one project where I first noticed the problem. Checking and unchecking the calculation order just rearranges the morphs but does nothing to put them in the proper nested order. I've gone through each of the body parts and they all have calculation order unchecked so I'm pretty sure that's not the problem. Thank you so much for your response, any further thoughts on what might be causing the problem?
