>>2432700sometimes pmxeditor fucks up when you pose or edit the bones in transformview (a lot of tsumidango models suffer from this), either is a bug of the editor itself or the modeler weighted them in a funny way that is too complex for the program.(fixing a bug shown in the editor in those tsumidango models ends with their arm rotational bones fucked, for example)
sometimes i think it's also because in mmd, the bone you move works along with another one that is hidden, enable the hidden bones and click and scale them just like you did with the normal bones. sometimes even reversing the scaling but only in the hidden bone can fix it, but it's a lot of trial and error.
