I had somehow acquired the Gofannon Quest line for the Sniper Rifle on my Titan. I had also current progress for the Auto Rifle for the Volundr forge. Both quest lines were complete to the point I just had to run the forge for both and complete the forge to acquire the weapon. I joined a clan game to finish the Volundr forge and it gave me the auto rifle. When I went to go to the Gofannon Forge because I had clan mates ready to try that out. The Sniper quest for Gofannon was gone from my pursuits. I went back to Ada and tried to purchase it, but nothing was there. Is this expected? Why did it disappear? If it was only supposed to allow me to have two active quests, how did I get both and was able to progress this both and then lose one?
