Has anyone completed this feat bat tracking by calculator? I have found 9 out 10 in batcave metal part 1 alert. I have found 8 before I get to bane.
The last one is in the Bane room, so you should have 9 before the fight (also one in the hall just before Bane). All are at ground level.
Did you get the one behind the pillar in the room with the two turrets? Did you get the one in the cove to the right when the main path turns left?
Just a friendly note: you don't get automatically teleported to Oa, so if you don't get the feat before beating Bane, you can still go back and search if you want. Once you actually go through the teleporter thou there's no going back.
