-The plot branches at three points depending on the decisions you make so once after you've finished the game you'll need to go back and do either Nundu Bay or Jennur's Horde, either Rilohn Refuge or Poghan Passage, and either Dzaganur Bastion or Dasha Vestibule. The latter two will depend on whether you chose Margrid or the Master of Whispers, and the first will depend on whether you chose to help Koss or Melonni.
-If you have done those missions, you must have just missed getting master completion on some of them.
