So after playing on my main character for about 4 days total the save says, I can no longer talk to any of my following companions. I can talk to people who aren't my companion easily enough, but anyone who actually is my companion I can't talk or trade with.

I was able to partly fix it by having to tell a follower to wait everytime I need to trade with them, but they still won't talk. This is really annoying, especially because I got Nick into some power armor, and now I can't get him out of it. I told strong to come with me but that doesn't fix it either it seems.

Basically game breaking if you have companions with you. :/
