I just did some side quests after Tuchunka (I forgot how it's spelled exactly, sorry.) and I went back to my ship to speak with Garrus, because he's one of my favorite characters. I find that he isn't there. I press V to open my ship map, go through all the areas, and he's nowhere to be seen. Everyone else is there, and I'm pretty sure I didn't do anything to make him leave. (If that's even possible.) It's sort of worrying me, because he's the most important person that I take along on missions. Yes, I've become attached to a video game character.
But seriously, is this a glitch or did I do something in-game to make him get fed up and leave?
