Forbidden Knowledge (Far Harbor)

Forbidden Knowledge is a quest in the Fallout 4 add-on Far Harbor.

Detailed walkthrough
Upon the discovery of Acadia and while allied with the Institute, the Sole Survivor has the option to inform the Institute of the existence of the escaped synths in this location. The Institute will then send a team to Acadia to subdue and capture the escaped synths. The player character needs to speak to Dr. Moseley to begin the raid of Acadia. After a brief battle, all escaped synths are teleported to the Institute.

Bugs

 * This quest appears ill-suited to the perk Intimidation, and using it during the quest results in several bugs. First, if used on any Synth refugees, if successful they become a lower priority for the Synth troopers, who will attack the ones currently firing on them first. Once those are killed, they will then open fire on the Synth refugees that have already surrendered, and keep firing until they are dead. For named characters, Intimidation works on some of them but not others, but the effect is the same - when finished with those actively fighting against them, they open fire on the surrendered named characters until they go down. Oddly, despite being on the player's side, Intimidation works against the attacking Synths as well. If Intimidation is used against William Moseley, he will briefly raise his hands as if to surrender, then begin running away to flee the battlefield as he no longer has a weapon.
 * The synths will not teleport back and will follow the player character outside.
 * Upon talking to William Moseley about the synth refugees, he will not acknowledge you and will continue what he is doing.
