i went to an unoccupied system within the sphere of a fortified system, and collected stuff from power wreckage POIs. The galmap PP description does say this is a valid activity there ("collect escape pods").. but when I went to turn it in in the same system I got no merits for it (I tested with one item, knowing maybe it wouldn't work); I thought, ok maybe I should turn them in to the Fortified system, which I tried - nothing. I tried the local Stronghold - nothing.
Items from unoccupied systems are of no use, or... explain?
