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 the escaped synths are teleported to the Institute.
Speak to Dr. Moseley.
After informing the Institute about the existence of Acadia, a team was sent to the island to deal with the situation. I need to check in with Doctor Moseley, and let him know it's time to reclaim the escaped synths.
Subdue the synths in Acadia
After informing the Institute about the existence of Acadia, a team was sent to the island to deal with the situation. It's time to reclaim the escaped synths; once I arrive at Acadia Institute forces will join me.
Speak to Doctor Moseley
All of the escaped synths in Acadia have been successfully subdued by Institute forces. I need to check in with Doctor Moseley.
After being informed of Acadia's existence, a team from the Institute has successfully re-captured all of the escaped synths living there. They will be re-purposed and put to work once more.
As long as Dr. Moseley is not spoken to, Acadia will not become hostile and any Acadia-related quests can still be completed, including Close to Home.
The game is not actually teleporting synths from Acadia to the Institute or elsewhere, it is just animation. They all stay in Acadia, disabled.
All Institute personnel and subdued synths are instantly teleported, but dead bodies remain where they fell.
PC This quest appears ill-suited to the perk Intimidation, using it during the quest results in several bugs: [verified]
PC 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.
PC 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.
PC 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.
PCPlaystation 4Xbox One The synths will not teleport back and will follow the player character outside.[verified]
Playstation 4 Upon talking to William Moseley about the synth refugees, he will not acknowledge the Sole Survivor and will continue what he is doing.[verified]
Playstation 4Xbox One After killing all synths in Acadia during the quest stage "Subdue the synths in Acadia," the quest will not move on to the next stage.[verified]
This can be fixed by exiting Acadia and killing them once again when they spawn outside. Then, furthermore, entering once again and repeating this process until the quest stage moves on.
Alternatively, wait for Moseley and the assisting synth troopers to enter the observatory before charging in. Make sure that Aster is the last synth downed in combat.
