I know this is a very old thread but i just got this bug after replaying this game so many times. I'm not really sure what to do since i pretty much finished everything before I did both loyalty missions of Mordin's and Grunt's. Grunt's mission is the only one not automatically working when i talk to the shaman to trigger it. Using gibbed didnt really help much, since the mission is still active in my journal not completed. I've tried using gibbed to change his loyalty, but once i head back into the game, the mission is still not completed in the journal, but people are talking is if it has been completed. And when I do talk to the shaman to see what happens, it's just the conversation of stories to tell him, and when i opt out of it, I get an automatic mission report that the loyalty mission is complete. BUT the mission in the journal is still active. AND when I try to talk to grunt in the ship again, he is talking like he is still waiting on the loyalty mission to be completed. Is there a way i can just manually do this mission cause right now i have this really annoying bug. I still have other missions to do loyalty or otherwise, I'm not sure if doing those first and coming back for grunt's loyalty mission might change anything. Again this is an old thread, I havent come across this bug until now despite playing this game for years. Thanks so much if you can help.
