For an example, in the Mirkwood scenario. When I fully explored "the old forest road" as activated location,did another copy of "the old forest road" in staging area get discard or doesn't contribute any threat point while?Or even it just stay in staging area and act as a distant threat ?
Treat the names as irrelevant. So all locations in the staging area count their threat, no matter what their names are. If you want to be thematic, assume that there are threats in different parts of the forest road.
