I cant find the encryption key after defeating the "killer" in the mission "What lies beneath" in the drozana station.
According to the walkthrough I just should "have" the key after defeating the killer. But i don't. Also mission still says "Defeat the Killer and Find His Encryption Key", although I already defeated him.
There is a circle on the map, approximately where the killer was, but there is no key.
I repeated this mission-part multiple times with the same outcome .
