Hello, I just completed the castle mission, and I had some open quests to complete by talking to preston,

after I completed the castle , preston glitched and talked to me about the other quests, instead of the castle,

then he talked about the castle, now he just says his greeting and I don't get any options to follow trade talk etc.

and to top it off, building at some settlements just does not work (build meter is not near full)

is there any way I can give you a save file to anolyze?
