Looking over the description for the Frozen Asset trophy I see there should be 4 side missions. On my Good playthrough I helped the Ice Soldier and...none of the other missions showed up.
I haven't completed the rest of the non-Ice Soldier side missions, but I've completed the game and am on Chapter 40: Aftermath. I've never done an evil side mission in this playthrough, yet I don't see any of the other three Blue side missions for this quest and I haven't gotten the trophy.
Do I have to get this achievement before the end of the game or are there some other conditions at work?
