I finished the first 2 encounters in Duality and had to take a break, was in orbit when I came back, but had boss checkpoint (Caital). I FINALLY beat her, but didn't get the triumph? Is this a bug or does it have to be in one playthrough. I'd be pretty upset if this was the case as it doesn't say you have to, just to beat all encounters solo, which I did. Will I receive credit for completing this?
