My reasoning behind the reduced action comes from the haversacks special ability. "When the wearer reaches into it for a specific item, that item is always on top. Thus, no digging around and fumbling is ever necessary to find what a haversack contains." I interpreted this as "i need a sword for my ally who's sword just broke/was lost. i reach into the haversack, the item in question that i'm looking for is now right on top", as per the haversack, which removes the need to dig through/search my pack.
Any thoughts?
Btw i really appreciate the feedback :D
