Prior to the "First FIrewall" mission, I was currently at the step in the Redbull Quest that required beating the S.A.B.E.R. strike. I then did the first part of the Sleeper Simulant quest, and repaired the IKELOS Fusion Core today, and went to banshee to turn it in. I saw the dialog on the screen for the new quest, but the quest didn't show up in the quests tab. Thinking that the Redbull quest might be interfering, I went ahead and completed it. However, I fear that my progress of the Sleeper Simulant quest has been erased. Am I missing something? Please help.
