Had a bug in agroprom. I got the code for the safe from a dead stalker in garbage, but when i went there, they wouldn't talk to me. The entrance guy wouldn't say anything, and i couldn't lure their boss because i didn't have the option to talk to him. The only strange thing that I did was going to agroprom before talking with the trader and shooter, that's the only difference that I found watchin a video from a guy that worked perfectly.
