Encountered the falling glitch while on the Firefly portion of the game. I was on my way to defuse the final bomb on Pioneer Bridge during the FireFly missions and when I opened the door from the train depot to the outside portion of the bridge to disable the final bomb, batman just started falling. Now all he does is keep falling. Unfortunately If I restart it just starts me at this point and I just keep falling.
I guess this means wait for a patch or restart the entire game which stinks especially since I was at 96% with the Riddler case file
