This is an annoying bug in the PC version where when you find an Enigma Datapack and tag it, it does show the tagging process but doesn't show the Datapack on the map. The only workaround right now is to find the Data Handlers and interrogatte them; only then you can see those Datapacks on the map.
I humbly request WBM to please fix this along with other reported glitches/bugs.
If you look closely at this scrrenshot you can see a figure in the top right corner on top of the building. Could this be man-bat?!?!??Batman: Arkham Knight General Discussion | 3 hours ago
