Dead Paladin Dance and shadow of Steel (Fallout 4)

I saw this issue on this topic, but unfortunately it did not help me.
The fact that I joined the ranks of the Minutemen and wanted only them to rule the Commonwealth, so began the war in the Brotherhood of Steel, by killing Paladin Dans almost from the beginning of acquaintance)
Now there's a bug where you need to talk to Dans.
I come, with all the shooting, and the task "Talk to Dans" and weighs, though I'm already standing over the corpse :
Cheat codes: it doesn't help , it's still going to come.
Have an idea how to solve?
Thank you for your attention)
