-- Playing on the PC -- I ran into this problem and searched for ways around it without straying too far from the play-through. Nothing worked, tried reloading my saves even back to before Raven Rock. Eventually what I did was to go back to the Lab in the Citadel and before I got down to where you "freeze" and all the trouble ensues, I did a quicksave.. then did these steps 1. ~ enableplayercontrols 2. unequipped my armor, equipped a fat man and blew myself up forcing a reload.. (it helps with some crashing,so I did it just in case..) 3. Respawned 4. *OPTIONAL* Because she wasnt there, I spawned Sarah Lyons with ~player.placeatme 0001d430 (her base ID) she then walks down to join Elder/Scribe 5. ~ setstage 00014e91 60 to force quest trigger into granting me "Take it back!" quest.. (Note: Liberty Prime won't move etc) 6. ~ CompleteQuest 14E8F (Quest ID of "The American Dream") which completes it leaving "Take it Back!" 7. At the Enclave barrier ~ tcl (since we have no LP to break the emitters) 8. ~tcl after going through the barrier (to turn collision back on) 9. walk to the gift shop entrance where Sarah Lyons should be waiting. (if you spawned a 2nd one earlier, yes there will be 2 of them! don't panic) 10. FINISH =) Also mentioned in another Thread, you can go Here and see another method. I haven't tried this yet. (Thanks to AlfredTetzlaff for this.) <-- Have since tried it and it wouldn't work for me.. so I tried.. Loading a save after Raven's Rock but before I went into the lab. while standing in the Citadel courtyard I used ~moveto player 0001d430 (her base ID) or 0001d44f (her Ref ID) to move Sarah Lyons to me; she then walked her assigned route down to join Elder/Scribe (and I simply followed her) then I chose the "I need a minute" and went off about other quests. *note, I deactivated all my mods after trying the way mentioned here because it didn't help; then used my 2nd method. got the conversation done.. went back to courtyard. saved.. and reloaded the game with the mods active (a bit of a pain to collect companions, gear stashes etc again. but better than a broken game I thought..) I hope this helps. its my first post. (Edit = fixed spelling error, added other method)
