Just finished raid in about 2hrs. We went into orbit as a fireteam then back into raid to do keys. During the raid I saw the keys acquired on my screen but I never checked to see if they were there in the inventory. When we got to the first chest (engine) I couldn't open it. That's when i noticed i had no keys but my whole fireteam did. Now I'm unable to get loot or finish Calus challenge. Help please??? I believe it was engine key, transfer, and I can't remember the 3rd one.
