I need some confirmation from others on something I just noticed in my new 0.34.07 fortress -- bolts apparently stack!
I have had a couple of migrant hunters show up. When my first caravan arrived, I selected to have both stacks of ~35 bolts each that they arrived with moved to the depot in order to get more trading (focused on defense due to my neighbors, goblins (War) and a tower, so I didn't have very much to trade). When I went to trade I realized they were bronze bolts, so I kept them to smelt down for weapons grade metal as I haven't located the supposed shallow metals on this embark yet.
Wile checking just now to see if my furnace operator had stopped burning wood long enough to melt some items, I noticed that my stocks screen listed a single stack of 74 bolts set to be melted. When I marked them for melting, it was separate two stacks. Checking my storage room, the ammo bin contains a single stack of 74 bronze bolts!
This is an important !!science!! discovery, and it needs to be replicated and validated! If true, the days of dwarves picking up single bolts are over, and collecting used, unbroken, ammunition is useful again!
[edit] Bah! I'm apparently not really awake, as teh bolts are not grouped in the bin. I could have sworn I saw them that way.
