Again a bug. (Fallout 4)

It's not bad that the minutemans from the BS lit it up, not like these half-dead people from the institute. To complete the quest, you need to talk to the grandma of all the minutemans, but she, acre like the weather, rheumatism and the arms trade, does not want to talk about anything. At the airport itself I decided to look for Dan. I did not find it, the current can be heard as he runs and swears somewhere nearby. Perhaps behind closed doors where no commands are displayed.
It can be cured like that with a medicine or only with a surgical intervention, a console.
