Okay, so I lost Danse..this hasn't happened before on any of my saves but it is annoying me to the point where I've searched every location I've been with him, twice. I finished the game, with the Minutemen so I still have both RR and BoS in the good books with me and each other. I've also finished Blind Betrayal too. But when finishing the game, I went to the castle with Danse as my companion and moved Shaun to Sanctuary. I didn't dismiss Danse as a companion when I went to Sanctuary, but he didn't show up with me, so I got Deacon to follow me and dismissed Danse to Sanctuary. Still no sign of Danse, ive waited 3 in game days for him to show, but nothing. I even traced my steps to and from the castle, to see if he's in any battles or stuck.. But nothing. I had the same problem with X6 as well. But he was easy-ish to track down, but still couldn't find him offically. It could be a bug with the new update, but I don't know.. Any and all help is appreciated, thank you.

There can be 3 things going on:

1) He needs more time to come to the place.

2) He might have returned to his default place instead(this is kinda like bug).

3) He might have ended up dead while trying to go to SH.(this is also a bug that can happen from time to time)

Surely just reloading a save is the simplest solution...
