Made a video where you can see the broken animation as the 2H Swords are "rolling" around your hands, but the hands are not moving.

There is another issues with Assassins and their wires connecting the backpack and the swords. If you have a 2H sword, one wire is connected to nothing (floating then). If you have 2 one-hand swords, all is fine... until you have cinematics or animations that removes the swords, but not the wires that are floating.
