Scrapped Important door, help?

Heya everyone,

So I was clearing out the Castle after I Claimed it and was just scrapping everything that seemed useless. Managed to find myself the pile of rubble, and walked down to only see a door, and I decided to scrap it too and continue scrapping anything I found, which was a brick wall behind it.

Now I've played 20 more hours mostly setting up settlements to be my farms, and just generally killing people without doing much story.

Now I've come back to the castle and talked to Ronnie, she says she's happy I've cleared the scrap and should enter the next area.

This is my problem, I'm not stuck, the door has been salvaged, there's nothing to click on or enter. Maybe I can spawn in the door with the console if someone can give me the object ID, or if someone knows a fix that isn't restart or go to an earlier save? There's also no quest marker or anything.

My next question is, why was that door able to be scrapped for wood in the first place?
