I can see the problem. The pivot of torso_g has a static rotation and the mesh is rotated in the opposite direction relative to it, so it looks okay when you view it but when you load it into the toolset or the game, the pause1 animation from the a_ba supermodel kicks in and sets the orientation of the torso_g pivot to something more like zero.
To fix it, go into GMax (or 3dsMax, whichever you are using), select torso_g and under the hierarchy, set "affect pivot only" and zero the orientation.
