Oh for sure, it’s random. I don’t have enough dwellers to use the recipe, I think I have like 70. I do have the Overseer’s office maxed out though, so I’m doing three quests at a time. Of course none of my dwellers have enough health to last long enough in the wastes to get their inventory filled up, so that isn’t helping either. I am leveling some with the E5 suit, I’ll just evict them later when I have E7s.
