Rigid Body simulation distorted after changing pose

[roycramer]

The cloth baking seems to work fine (though I have to use "build" and "clean" quite a lot, and they take a while) except when I try to change the pose. I can't exactly tell what's going on but it seems like the rigid body locks to one area. I've had one result where the skirt and hair will try and get as close to the origin point as possible, if I move it away from there. Do you have any fix? I included a blend file too if it helps.

It seems I've solved my own problem, ha. It seems doing this order of commands:
(spacebar menu) free all physics bakes
clean
build
(spacebar menu) bake all physics
seems to reset something.
Maybe you could make this occur automatically? Still not sure if it's a perfect solution.
