My Worgen Warrior, being in Fury Spec, after combat always remains visually with his weapons out. And even if the jump animations and so on show his hands as if he has no weapons, visually they are still there. Imagine how it looks doing the Running Wild mount after combat, running around in four, having both weapons in hands. This is a visual bug, I don't know if this happens to other races as well, but to my worgen sure does.
