Shaun is in the hands of the Institute. I need to find this place and rescue my son, but in order to do that, I'm going to need some help. Nick suggests we talk to Piper and see what information she might have.
It would seem the only person who knew the way into the Institute was Kellogg... and he's dead. But there may be a way to access his memories. Doctor Amari in Goodneighbor may be able to help.
Once Dogmeat has found Fort Hagen, he may become stuck at the front entrance until entering Fort Hagen. [已核实]
If Dogmeat finds Ness along the way to the fort, they will attack each other endlessly, rendering the quest impossible to complete without traveling to the fort yourself. [verification overdue]
After using Kellogg's terminal a bug happens where any robot companion that you have made to join you has their name reverted to Automatron. And cannot be changed. No known fixes other than reverting to a previous save. [verification overdue]
Players engaging in non-standard playthroughs where Codsworth, Preston, and Dogmeat are all ignored may trigger a bug where Kellogg's dialogue does not trigger in Fort Hagen, leading to a situation where the final door will not open, despite all the synths at Fort Hagen indicating that they are defending Kellogg. This can be fixed relatively easily with tcl and/or disabling the final door with the console. Kellogg is unable to be talked to, but can still be killed as normal to complete the quest. [已核实]
Hacking The terminal within the fort results in bug that prevents the mag lock doors from opening (even if you have the password). [verification overdue]
