"Seek and you shall find" Broken?

[Wendygoon]

Is this quest broken? I've collected all the stashes, the last one being in the swamp since it was so far out of the way. Got the rifle, quest still pointing at the stash, opened it again and grabbed the 2 flash drives that magically spawned. One says to go to Pripyat but the quest wont update and is still pointing me to a now empty stash in the swamp. Any solution to this?

it surely is broken. "M" button to show on map doesn't work, I have two stashes listed, and none of them appear on the map. this game is so bugged
