Hello I'm currently stuck in a bug on the mission nuclear option, im at the point where you teleport the minuite men into the institute and the next step is to talk to Preston Garvey but I'm unable to engage in conversation. The problem I have is you can't fast travel away, the room I'm in is sealed so I can't back track and all my game saves are at this same point. Is there a fix for this bug because i really don't want to start a fresh game due to this small bug, any help would be appreciated.

Exit the game, close it down, see if that helps.

Try talking to everyone.

Try shooting him. Seriously.

Try dismissing your follower.

Preston Garvey and his Minutemen bullcrap should be renamed as 'Glitchstitute'

Hey thanks for the replys but still no luck.

Bumping this for the chance someone has the answer.

Did you try my suggestion?
