The cul;tists after Dragon Born was installed won't disapear and they are in white run

I have tried sleeping in riften for 7 days but they still won't go

Any ideas how to get rid of these bodies

I'm planning on turning them to ash outside whiterun

P.S. Even Ulfrik's body doesn't appear in windhelm it's been there for a while panning on turning them into ash too.

None of the people's bodies you have mentioned get removed when the cell respawns. There's nothing you can do about that.
