I'm on the last step of the Kepler fabled questline, and I only need the strangelet capsule from the invitation mission (Outer Steppes Strangelet) but after completing it multiple times on fabled difficulty and picking up the strangelet at the end of the mission, I never have the strangelet actually added to my inventory and thus can't place it at the altar after completing the mission. I don't have any other capsules in my inventory and have tried everything to resolve the issue, from deleting the quest to clearing my Steam cache, but nothing seems to help.
