When I succeed at such a hack and then extract, on the loot screen I get something like:
This part is absent if I extract without hacking that lampost.Artifacts
Alien Artifacts are not recovered when XCOM evacs from a mission.
Supplies 35
Does it mean that hacking for resources is pointless, as they are going to be lost either way? Is it only useful on missions without timers, where you manage to obtain corpses etc? Or do you have to do something (what?) to actually extract those resources after a successful hack?
