I'm having a similar problem I've just finished Kikowani Station & currently doing Mombasa Streets but I can't see a beacon for Data Hive the only locations in my VISR are
ONI Alpha Site
Also it seems I didn't get Super Sleuth and I went through the entire level without quitting or anything. Ive got the achievements for completing all the other levels before Data Hive so I don't know what I'm doing wrong. Any help would be appreciated.
