IF YOU'VE JOINED THE BROTHERHOOD OF STEEL We wouldn't be surprised if Bethesda modifies these events with a patch.
It feels like a bug, given that we'll show you how to earn 300 XP without doing much of anything. The latter details the game as of November 2015. Read THE CASE OF THE MISSING QUEST, our alternate walkthrough and explanation, to learn what could also happen. Read the IF YOU'VE COMPLETED REUNIONS section for a quick explanation of what you need to do and where you need to go. Because of that, we've split this walkthrough into two parts. Note: In two separate playthroughs, we verified that, if you join the Brotherhood of Steel before starting Reunions, this quest will not appear.
