When trying to replay the Kepler story missions on Mythic to get the Strangelet Capsules, I don't keep the Strangelet Capsule at the end of the mission "The Invitation." After putting the Strangelet Capsule in the device at the center of the main area from the boss fight and watching (or skipping) the cutscene, the buff disappears and I don't have the Strangelet Capsule to integrate back in Caldera. The first time I tried last night, I put it in immediately and didn't keep the "Strangelet capsule charged" buff after watching the cutscene again. I finished out the mission, no capsule back in Mythic Caldera. Tried it again the next day after getting one of the secret Strangelet Capsules and waited out the 30 second timer on the buff to run out before starting the cutscene that time. The Strangelet capsule charged buff disappeared completely and it still wasn't on me after I finished the mission.
