Im currently reinstalling my citadel dlc for ME3 but I'm already in the middle of my playthrough would I need to restart it in order to play it or should it just pop up when I boot up the game.
I believe you need to restart
We had a similar question regarding 'from ashes' some days ago. It seems like an active playthrough cannot access a major story dlc.
No I got it... I didn't need to restart
And how did it work?
Exit Game or reload your save file?
Don't know I was at the citadel. I turned in some items for assignments then went back the the Normandy and traynor was like "you have a new message at your private terminal" and I was like would you shut up, but the message was there.
You don't need to restart, just load the save file (or the game just to be sure) and near the end of the game
you will get an email from Hackett about shore leave, just go to the citadel and then fast travel to Hackett's apartment.
What do you think?
