Actually, Sun's animation in Vol 1 is from an old thing he made for educational purposes.

And with the re-rigging that Monty did in Vol 2, he may have fucked up Sun's weapon's rig and caused it to just plain not work with the physics system that they now use. The last thing he discovered prior to his death may have been a workaround on that.
