I'm trying to complete a few of the missions that involved finding pieces during the Tuchanka mission set. Specifically:

  • Benning: Evidence
  • Citadel: Improved Power Grid
  • Citadel: Barla Von
  • Citadel: Heating Unit Stabilizers
  • Irune: Book of Plenix

However when I complete the missions on Tuchanka that give me the requirement pieces (like opening up Irune and Benning for scanning, exploration), it immediately starts the "Priority: Citadel" mission set and I cannot turn any of them in.

It probably should be noted that Sur'Kesh and Palaven priority missions were already completed. As in, when I completed Tuchanka, the above listed missions are greyed out.

Aside from editing my save file to say the missions were completed, how can I do these missions without resorting to such? Is there something that I missed. Should I restart and do Tuchanka's mission set first, turn those in and then the others?

Priority: Tuchanka is a turning point in ME3, because once it's over, it automatically triggers Priority: Citadel. During that mission, you cannot complete any other assignments. Once Priority: Citadel is completed, certain assignment are no longer possible to complete, due to a rearrangement of NPCs on the station.

Benning: Evidence, Citadel: Improved Power Grid and Citadel: Barla Von are part of those missions that cannot be completed after you've started Priority: Tuchanka. If you want to complete these missions at this point in your game, you will have to either load a save file prior to the start of Priority: Tuchanka or edit your save file. It should be noted that Benning: Evidence is not completed by scanning the planet but by doing the N7: Cerberus Abductions mission, which becomes available upon completion of either Attican Traverse: Krogan Team or Tuchanka: Turian Platoon. If you have completed that N7 mission without finding the required evidence, you should check out the Spectre Office.

On the other hand, Citadel: Heating Unit Stabilizers and Irune: Book of Plenix are impossible to complete before Priority: Citadel is over and you will be able to finish them afterwards.
