Nope, I tried that.

I don't just mean its off by a little bit. It literally fires at a point halfway between the centre and top of the screen. It almost seems like a grenade lob? Which would make sense if the weapon mesh disappears and the class-label is "grenade". So how did they make the mortar launcher work?
Another slightly weird thing: the map crashes unless I move the AnimationBank line to just under the geometry. I guess there's something weird with the animations involved...
EDIT: After tweaking it based on the ewok spear (thanks Mav!), its working a lot better.

I still need to figure some things out, but at least it fires straight.

Here's my new files:
Crossbow:
Ordnance:
The problem I'm having now is that while the ordnance stays around and sticks to things, its always directly perpendicular, which is totally ridiculous.

It doesn't keep the rotation that it had when hitting the object. So it doesn't matter what angle it hits the ground at it always sticks out vertically. I checked out the ewok spear and its the same.
