Hi, Sober.
I did not install yours mod. But we shall think theoretically.
I think, a problem is in bad joining (connection) POS_Head_04 with Body_01,
because POS_HEAD_04 has special features of geometry.
At me a question, how you have solved a problem, if you did not change
POS_Head_04 (or Body_o1) geometry and connecting of this head with Body_01?
You have moved heads from one folders to another only. :hmm:
Look pic's:
