After a long-ish playthrough of Just Cause 2 on PS3 (about 20+ hours, completed the story, about 35% completion) my parachute won't open. Ever. I press the X button (jump/parachute) and nothing happens, even when in free fall (jumping out of a plane/helicopter) or grappling. No matter what I do, I can't open my parachute.
I've reverted my controller settings to default (and ALL settings, just to be sure). The Controls screen still shows X as the control for parachute. Doesn't work, ever. I've restarted the game, the system, no luck. Saved, loaded the save (not from autosave). I tried switching from the default parachute to the red DLC parachute. Nothing has worked. The parachute does work on a new save, and on a much older save.
Is there anything I can do to get my parachute back? The game is completely unplayable without it. If this glitch is permanent, how can I avoid it if I have to go back to the old save?
