I'm having a bug re-recruiting Arcade Gannon. When I'm doing his companion mission I get to Jacobstown and talk to the doctor. After that I tell him to go back to the lucky 38 so i can take the grandma supermutant to do the doctors quest. When i get back to the lucky 38 there's no option to re-recruit him as a companion. The dialogue option doesn't even show up. But when i recruit another companion then talk to him, it does show up except he can't join me because I already have a follower.

I've tried everything. I've tried to reset him in console. I've tried recruiting a follower then entering the dialogue, removing the follower and trying to get him to follow me again. Nothing works. I did notice when I disable and enable a follower in console there is something like "package sandbox" or "package follower" is there a way to set arcade as a the follower package? Has this happened to anyone else?

I have no idea but is there a option to send him out of the Lucky 38 back to Morman's Fort or what ever? Try that and go to him there if possible. If no I have no idea sorry.

No theres no option to do that. No option except to talk to him about himself or about whats going on right now.
