Bugs

 * When doing Leading by Example on normal and being told to go to Bedford Station to clear all hostiles with the squire, you can clear all the hostiles and the quest won't end. When changing the time to evening so that new hostiles might appear, killing them still does not end the quest. The only fix is to load a save that was before you picked up this quest line.
 * Sometimes after completing the story for the Brotherhood of Steel, Lancer-Captain Kells will ask you to inform him when you are ready to head out with another squire endlessly, preventing you from ever doing this quest again. After choosing the peaceful option on the quest A Loose End and completing it, Kells will get bugged and these radiant quests cannot be received anymore.  after he bugs out will fix this and make it so Kells will give the quest again.
 * Whenever you talk to all the squires it does not progress.
 * Sometimes the game will crash upon entrance to College Square, making the quest impossible to complete. Consequently, the Brotherhood Squire will continue to follow the player for the remainder of the game, making Institute quests with X6-88 impossible to complete as X6-88 will become hostile to the Brotherhood Squire.
 * When sent to University Point the area may already be clear making it impossible to complete the quest. advances the quest and possibly is a fix to the College Square bug as well.
 * You may be tasked with clearing University Point of Synths when friendly with the Institute, meaning the Synths in the area are not hostile. This makes it impossible to progress with the mission. Compounding this, if your active main story quest is Synth Retention, you cannot progress with the main story as the Courser will endlessly fire upon the Squire.
