Are all items found in all scavenge piles? Or do only some parts, say of a cart, fall one place while the rest fall only in another place. If so where can we find this list? Or is this just wonder around blind hoping to find the right pile just by chance?
I do see that higher level items, craftsman adept, fall in higher danger levels. But am I more likely to find item X in pile B or does item X only fall in pile Z?
