Checkpoint saving glitch

Broken campaign, can’t get passed Act 2 part 1. The part when you need jack to shock trap a generator and open door. This is the second time its happened. Now I have to go back to the end of Act 1 then do all the walking around and collecting (which I hate) over again…Nope I’m gonna contact Microsoft and request a refund for for this, maybe I try again once TC FINISHES the game. I mean I know the folks at TC get worked to death to make a deadline but how do you launch a game with a broken campaign? I don’t NEED a game on a specific day but I DO expect a game to be playable when I purchase it.
