Modding SW3?

Damn, adding sound effects to Rockets.xml is bugged. Notice how all entries have blank <work_sound> tags? (They are just declared as "<work_sound/>".)

If I attempt to add a sound, e.g. <work_sound>horn3_2.wav</work_sound>, the sound works (but it's repeated as long as the missile is flying, so it's kind of odd), but the game CTDs when the missile hits the target. Unfortunately LOGfile.txt does not say what caused it, it just complains about memory access violation. Damn.

Also, I cannot find where the missile firing sound is called. I know the file, it is "s_rocket_launch.wav", but I cannot find references to it. The game just plays it as if it were hardcoded

This is unfortunate because sounds are defined and used in Carcasses.xml and they seems fine there.

Edit:
Here's the error. I tested on the T3 Supernova Torpedo since I didn't mod that one previously. Without sound = ok. With sound = CTD upon explosion.

As you can see, nothing is wrong prior to that. I fire the torpedo and watch as it flies to the target (and the sound file plays while it flies). As soon as the missile hits target and explodes... CTD.
