---This post contains spoilers about a companion---
I've came across the police station with the BoS guys, did the first mission with Paladin Danse (here I took "Unsure" while having Preston with me when asked by Danse if I wanted to join the BoS) and helped out the other two BoS members. Then I proceeded to join the BoS and did the second mission by Danse, looking for missing BoS members. After that I still can't get Paladin Danse to follow me, he only says generic stuff but no dialogue wheel or any option to get him to follow. Dismissing Preston doesn't help. What went wrong?
Edit: Why was this moved to Cheats, Spoilers, Hints? This is most certainly a bug, since I meet all the requirements to have him as a companion. I would need a technical workaround or a fix, not a gameplay specific hint.
Edit: Nvm, I read a crappy incomplete guide and made sure to let the author know, how crappy his guide is.
