I was in the Cherno building site, I was going to log off in the top floor stair case. I ran to the corner and pressed escape to log out, however I clipped through the wall and fell the 3 stories to my death.
30 minutes later my friend whom I was on Teamspeak with also fell through a wall and died, however the wall he fell through was in the Balota Air Strip. On the 2nd floor of the baracks he was looting something on a locker and he fell through the wall too and died.
