After my castle quest, Preston went back to his original settlement in Sanctuary on his own - didn't even tell me. When I finally find him there He starts throwing some one liners but I never have the option to trade or recruit him again.

I also had a really hard time doing the armory portion of the Castle quest with Ronnie. I had to restart the conversation a dozen times. I advanced a few lines of conversation only for it to be reset again and had to cycle through it quickly so she doesn't reset again.

Here's more info I had:
