The siege weapons on this quest rule, but if the people before you have used up all the ammo on the quest then you don't get an opportunity to try it yourself. Would it be possible to reset the ammo with the quest so everyone gets a good chance at this?

I wonder if it could use the loot spawn system from a "map chest" to generate x ammount of random ammunition types for the weapons. Then you'd have a chance of having all sorts of ammunition, including bodies ...
