various citadel side quests won't complete
On my fifth playthrough of ME3, and I've run into a glitch I've never hit before. Three different Citadel side quests are all having the same problem. For the Chemical Treatment quest, the Reaper Code Fragments quest, and the Target Jamming Technology quest, I overheard the various conversations, found the various plot items during the appropriate combat missions, and am now ready to give the items to the appropriate people on the Citadel. Except when I approach the appropriate NPC and try to engage, my Shepard simply repeats whatever dialogue was triggered by FINDING the item ("Oh, this looks useful...") instead of the dialogue that allows interaction with the NPC ("I overheard you earlier, and I've found this cool item I think will solve your problem...") Because the right dialogue isn't triggering, I can't give the item to the NPC and the quest won't complete. Same problem for all three quests.
For whatever reason, I'm not having any trouble with quest items I pick up via scanning planets; it's only with quest items found during combat missions.
I've tried quick saving and reloading, but it doesn't work. Tried exiting game and restarting; doesn't work.
I'm a completionist, and this is driving me nuts.
Playing on PC, via Origin download. Have all plot DLCs but not the alternate appearance or weapon packs.
