I just killed helicopters and saved Petrenko in the bar (metal factory) but now I have to talk to the Barman who escaped to Pripyat Outskirts (Chernobyl Town) but when I arrived the reach point there's no one, just a voice saying "go up here" but on top of the building there's a little room with two doors locked, no one inside, at the bottom the door I approched that told me that is locked too, and even more surprising I decided to go to the new Duty point and all the NPCs are HERE but INVISIBLE, and no interaction is possible. Anyone has this "bug" ? I am patched official Dez patch 1.30013, nothing else.
thx for help
