Have a bug with Hakon

[Беркут9/11]

As I said. In the mission when Frank told you that Hakon wants to meet you in the church I went there fought him but then smth went wrong Loan didn't appear and I just killed Hakon, then Frank phoned me, but checkpoint didn't change. So the mission has not ended, journal is saying that I need to kill hakon, but he is already dead. I really don't know what to do, I walked through this game second time and have the same bug in the same moment. Plzzz help

Frank didn't even give me this quest. Is it a bug?

you should have gotten message that Hakon wants to meet with you. then you go to the church. Lawan should show up after you kill him or even if you dont. so if she has not shown up something is bugged. because i played once where i killed him and she showed after. I also played once where i did not kill him and she shows up after and things play out differently. so if Lawan is not showing up it is bugged.
