Tried again, worked now...guess i missed once last time.

I can't fire more than 3 torpedoes...

I have a problem with the "Clouds of Vonduru" mission since equipping Proton torpedoes...while the item claims to give me 4 torpedoes i only get 3, and there are 4 shield generators which must be destroyed...not to mention the cap ship bridge for the bonus. Problem is, i can't launch missiles at the shield generators with proton torpedoes equipped, even if out of ammo...any way around this? Except unequipping them ofc...
