Attacking with saber while dying doesn't make the swing really end.

To replicate:

1. Start a new game, use the cheat code "Red5" to get a lightsaber.
2. Equip lightsaber and stand with your face to a wall (in lightsaber reach).
3. Open console, type "kill", do not apply it.
4. Ingame, do the alternative attack for the long swing
5. During that swing, open the console, apply the "kill" command

Result is that you're hitting the wall with that distinct "spark" coming off of the wall continuously while you're either in the process of dying or dead on the ground. This happens without the kill command as well.
