Ive encountered a bug where during the quest the last day of william wray im stuck as i have no option to use the elevator on the undisputed claim to go to aunties floor.

yeah I'm in the same boat I managed to talk the big moon head guy down. I didn't kill him maybe I should have. and now it says I need to go meet with Auntie but I don't have access to the elevator at all. 

Same here. I attempted to negotiate peace between both sides but ultimately wound up killing him, going against the dialogue choices that I made. I'm starting to think that broke the quest.
