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.

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?
