It's probly more obvious to spectating admins when somebody is dropping and picking up a crossbow and when somebody is actively looking for ammo. I encountered what seems to be the obvious problem. In one of the castle seiges, I ran out of arrows, but I found quivers on the bodies of my fallen comrades. But every time I picked up a quiver, it had no arrows in it. I don't even see why a quiver would drop if it was empty, let alone why it would happen 4 times. I'm pretty sure the code that says how many arrows a quiver has is set to the player rather than the quiver, which would mean picking up quivers is entirely useless after running out of arrows
