Can't get to Hyperion

My problem arose about 2 days ago. I've beaten the campaign on normal difficulty, 25/26 excluding alternative missions, so I went on a hunt for achievements. It went fine and I started collecting them nicely up until I got to The Dig mission. So, admitting that I'm not yet good enough to destroy 50 buildings on hard, I attempt to abort the mission... then arrive at the mission archives interface, I click close... and it kicks me out of the campaign and I end up at my profile. I've tried playing cinematics and then leaving the archives (not missions but I would assume the same thing happens) but it doesn't work.

Any suggestions?

 

I really need to finish the game to see if i can make any of this stuff happen. :/ I have no clues man. Maybe someone else does?

 

It's probably meant to be like that because one of my mates confirmed it. I probably only noticed this at the dig mission because that's when I first wanted to quit the archives... the preceding ones I tried one after another.

*facepalm*
