Confused about the Glitch
 

I haven't played the game yet, but plan to start it in the next week or so. I want to check on something about the glitch before I start.

I see people saying that to avoid the "Storm Shattered" glitch, switch to "Casual" difficulty on the 3 levels so you cant die. But if you do that, wouldn't you miss out on the achievement for "Complete every Mission on Hardcore Difficulty"??

Wow. A bunch of people looking and no one replied?
No one has any clue about this?

Helloooooooooooooooooooooooooooooooooooooooooooooo oooooooooooooo????
All these people that have the cheeve and not 1 person can answer me????????
:( .............

If you did just the one playthrough then I would say, yes it does, but you can go back and replay missions on hardcore that way you can avoid that glitch.

Confirm
 

So can anyone confirm that you can switch to casual to avoid the glitch and then replay the level and switch to hard so you don't miss the Hardcore achievement?
