Anyone else had campaign issues?

So, I started to play the game trough on legendary. It was going well until the mission “evacuation” where the game just froze at one point. I took the game disc out, started another game, inserted the disc back in, restarting the game. I loaded the last checkpoint (which was exactly at the point where my game froze) Well, my game froze again. I needed to replay the whole mission again.
Next time I had issues in the game was in the mission “reunion”. I played trough it normally on legendary, until I died. When it loaded the previous checkpoint, my game restarted. I tried to resume the mission like you could normally do, but my game just restarted again. I needed to replay that mission from the beginning too.
