One thing we'll need to check is whether the new mapping still works for the low-poly version. I've had a quick look at the torso map you posted some pages ago while still working on this, and saw that the seam between torso and neck was not placed correctly. Seams have to go along the edges of the low-poly mesh, or otherwise the map can't be used with it.
