In the beginning of ME3 I completed the Grissom Academy quest but after I accidentally loaded a save from before the mission and continued from there. I only just realized this +20 hours later and I'm almost done with the game, so there's no way I'm going to load the correct (and now very old) save.

Edit: I do have coalesced
