Batman Arkham Origins Burnley Glitch Fix

Discussing Bug: Burnley Radio station vent shaft. On Batman: Arkham Origins PC message board and forum (page 1). Recently, me bro & I discovered a bug in Burnley district's. Couldn't be bothered waiting for a patch:P. By now there is a Fix for the my alibi glitch, and that one might even work for other problems which occur once you enter a building. Found it in the steam forums and it works like a charm: 1. Find file BmInput.ini in your Batman Arkham Origins folder (eg: C: Steam SteamApps common Batman Atkham Origins SinglePlayer BMGame Config BmInput.ini) 2.

When you get to the Riddler's communications tower in Burnley, and get locked into the room, I can't seem to get out. I can grapple up to the event to escape, but Batman categorically refuses to climb into the vent. I can drop down from the vent and grapple back onto it, to hang from it, but I simply can't seem to climb in. For the record, I did pull the grate off the vent, and got the Riddler's sarcastic congratulation. Am I missing some cryptic key combination, or is this a glitch preventing me from getting any further?

Edit: I managed, after about 5 minutes, to do the 'trick' posted in the sticky. Had to use keyboard + mouse as I couldn't get it working with the controller.
