I have bought and installed Automatron DLC today! when i came back to Sanctuary to talk to Preston, i got stuck in conversation and cant get further. He tried to isue me a new quest, but we get stuck!,So no Minuteman Quest evermor(it was my first MM Quest)What a [censored] is this??

I wish I got that bug.

He always does this, it's not related to automatron. If he just sits there, just walk away and come back later. You're the first person I've seen get angry over not being able to do Preston quests.
