The game crashes when running through a specific area on the NE side of Berezino (called "lumber mill"). I have outlined the approximate area with a circle in the attached screenshot.
It should be noted that there was a group of 4 of us, and it happened to every single one of us individually. All of us crashed every single time we ran through that area, without exception. I also witnessed a 5th unknown person crash there as well. Once he ran into the area, it was evident his game crashed because he began to run through solid objects and never changed direction until his character disappeared. {F30485}
