Forum:End of "american dream" quest glitch

After escaping raven rock i go too the citadel to speak to elder lyons in the lab section.

when i get down on the lab i see elder lyons speaking with the scribe and sentinel lyons and when i approach she says something to him and then i cant move and the HUD disappears like when you talk to someone but then nothing more happens. it just stops there nothing happens people are walking around so the game dosnt freeze or anything lke that.

have the pc version
