Rigging; Head not staying on Body

[woodya9882332]

Puppet seems to be working well but head is not staying on body. Seems like most trouble shooting I read focuses on making sure both the head and body are not independent, which is how I have it set up; any ideas?

One thing that stands out is that you have two head layers in your hierarchy when you should have only one. Even hidden layers are registered by the program and can cause problems. If you don't intend for a layer to be used, it should be deleted. If you're concerned about losing data, make a copy of the file and then delete.

Also the origin marker for the head should be dragged inside the yellow outline so it turns green. There is also a head attachment strength in the face property that you may need to adjust
