The situation describe under the spoiler to protect certain individuals from solarov story)
Spoilerphobes, I took the quest where you have to teleport the Institute, and to talk with the father (my son),Desdemona (Chapter subways) gives me the quest Under the ground and under the cover of like we need the virus to enter in the comp and there with the subway to save agent synths..I teleported and get to the location of the Institute,a marker quest I go to the Elevator from there to the father there talk to him then have to go back to the teleporter,but I'm following the quest Under the ground and under cover brought a virus into the computer the closest and the quest indicated that I should meet with the agent.BUT there is not as it does not pass,the doors are everywhere closed,no access, etc ... the lift only moves me to the bottom, that is to say to the father,and in General the pavilion of the Institute, no..not like I can't go to that agent unless you first teleport to the Commonwealth then the quest automatically failed me..Well, I decided to cheat wrote via command line cheat to through doors,walls to get.All I got was this cheat out, talked and he said we should talk to Desdemona which is located in the subway ... Okay,went to the teleporter and through him teleportirovat the Commonwealth to talk to her, BUT exactly why the quest failed...Epic Fail
