I'm not sure how long the problem with my companions has been going on, but recently, I finished the mission to shoot down the Prydwen with the Minutemen, the quest I was given immediately after is called Defend the Castle. After fighting off 10 Brotherhood Vertibird's I'm told to talk to Ronnie Shaw, and Preston Garvey, but I can only talk to Preston, and anytime I interact with Ronnie, I'm forced into about either, wanting to trade gear, or looking to buy from her. I do not get a choice as to talk to her to finish the mission, to ask to trade, or to buy. She follows me around the castle, and when I'm withing 3 feet of her, the interaction is forced, whether I'm walking buy, or literally facing away from her. I could be talking to Shaun (Cuz that's where I left him.) and then I'm forced out of the conversation menu with him, just to say; " I'm looking to trade some things.", and see Ronnie's gear.
It might just be my game, because I had the Defend the Castle mission freeze on me 5 times, 1 having a Vertibird fall through the ground and keep flying below me, 3 forcing me back to dash, and the last one forcing me to hard reset my xbox.
About the companions, I have chosen to make my own personal harem, cuz fukit, so I romanced all the female companions, except maybe Cait, cuz her personal quest broke when she gave it to be, and now it just disappeared. But every time I talk to any male companion I've reached max affection with, they ask me about the personal conversation we had before, and no matter how many times I say "Thanks for your trust." Or any other option that isn't romance, after I don't talk to them for a while, they will ask me about it again. I've gone slightly into Preston's romance branch, but chosen to say, I still love my wife, I don't love you, or I don't know, cuz I don't want to date any of the males. This might be affecting the female companions, but I'm not sure.
I'm posting this so BethS can patch it, I'm like 99% sure there isn't another way to fix these things.
