On the un-nifskoped one, it's like this:
NiNode (Scene Root)
-----NiNode (with Isabella's crown stuff in it)
-----NiNode (with all the Champlain stuff, including the hair, in it)
ahhh. then for some reason it "remembered" Isabella's stuff. expand those out and see the trishapes. click on the hair and copy that branch and put it directly under scene root or isabella. not sure which one with out testingit myself.
On a second note this might mean that you left a "bone" try see if the model looks ok in-game, because you might have to go back to the blend.
