Are there any other special requirements regarding the sorties to unlock Recollection 21 (such as not returning to the Citadel during the sortie, perhaps)? Because I've done a lot of sorties with Nihongou and Hasebe together and still haven't gotten it to occur--but I do have to return to the Citadel in the middle of most of them. I just want to make sure I'm not doing something wrong!
