Was not aware that the side quests expired when you progress though the main story. I was like yeah sure "school is being attacked and need help" I'll come after a few missions. Then couldn't find the mission in the mission select and then came across an email that said they all died and maybe a ship got out but was unsure if any made it and it basically traumatized me. I don't think I played the game after that because I felt so bad lol.
