HI,

i killed all the Nightskin in the basemant and the quests updates and i have to speak with jason bright. But when i go upstairs to where all the ghouls are they won't let me in again and i cant complete the quest.

any help?

what? is the door locked or something? you don't need to talk to them on the intercom after the first time.

The door is locked, it says that i need key.

You can go in the "back-door" which is a manhole just outside REPCONN. If your standing at the rocket outside REPCONN facing directly away from the site, head briefly forward and to the right, there is a manhole behind some rocks. Apologies for lack of direction, I can't remember compass directions, alternatively you can check wiki for the location.

the manhole only leads to the basemant, i've already gone all the way round through the manhole and it doesn't lead to the ghouls upstairs

I have exactly the same problem. is there another entry to the lab?
i don't have a savegame bevore the bug and i really don't want to start a new game :/
