If you have also done Jack's Loyalty Mission, you'll be taken to the Normandy after doing Miranda's in order to resolve their fight.

The main complication is Miranda's Loyalty Mission.Tuchanka, the Citadel and Illium can have more than one Loyalty Mission on them at once, so it's possible to sneak in one as your fifth and then do the second on that planet as a sixth, letting you get more Resources, Research Data and XP. This requirement can be exploited: completing Loyalty Missions will not return you to the Normandy (Dossiers will, however). The Normandy Crash Site DLC also does not count, despite having its own level. Certain minor Side Quests do not count towards this, typically ones that do not have their own level, such as Struggling Quarian on Omega or Krogan Sushi on The Citadel.This can include Dossier levels, Loyalty Missions, N7 Side Quests, or DLC like Overlord or Lair of the Shadow Broker. You need to have completed five Missions and / or Side Quests after Horizon.For modern players, the addition of Zaeed and Kasumi early into the game means that, after Horizon, you only need one more Squad Mate to meet this requirement, assuming you've awoken Grunt. The acquisition of the Collector Mission is a bit nebulous, however there are a few requirements that are generally reliable: What Triggers the Collector Ship Mission?
