DEAD MAN PROMISE - Farm mission bugged, game breaking

[Jaso7]

About halfway in the DLC DMP, I cannot progress.
The farm mission (neighbours) needs you finding keys to open safe in the field. I've basically completed everything else in the game, but this prevents me from progress.
I've going between two different farms for hours, ghosts at the farms have no new stuff to say and the key to the safe simply isn't anywhere. I've checked all the placed recommended here, plus spend ridiculous amout of time looking for it elsewhere.
Isn't there an option to spawn a key? Like with a console command? I don't think I have it in me to start anew

Found out, that it's just "side mission" that's bugged, and even without the farm safe item you can finish the game. You just can't complete the ultimate weapon, don't know how much difference would that make. It's shame, though. Without looking for the key for hours, I've enjoyed the DLC as much as original game. Peace

If its the key for the safe on the farm i found it in one of the houses can't remember were.

For me, the key was on the shelf of the house on that's on your left side when you're facing the chest (the house that doesn't have a cellar and whose ghost says it hide the key at their neighbour's)

It was on the top of a bookshelf in one of the houses, I had to jump up to see it/grab it.
