WeaponFireSpecialAbilityUpdate problem

[Stygs]

I wanted to equip the GDI Slingshot with AA missiles as a special abillity - works so far, but only ONCE.
The SP reloads and I can use it again, but it will not fire any missiles.

Why?

Make sure the weapon has a ClipSize of 0

Made no difference :/

Also, I am using the juggernaut weapon and since the jugg can bombard just fine, its propably something else.
