I had started playing this mission and I made it to the point just after obtaining the gun from Nimbus. I had to stop the game due to RL stuff and figured I'd come back to it. The gun was gone from my inventory. So, I restarted the mission and when I got to the point of getting the gun again, it dematerialized like it does and then nothing. No new weapon. Then I realized that 'Rohan's Keypass' was consumed upon receiving the gun. I never got it back. I have tried to drop and reacquire the mission. If I drop it, it just restarts with 'What Remains,' not the entire mission chain, and without the keypass. Is there anything that can be done? Thoughts, besides don't start it unless I can finish it?
