I was just playing on one of the bistudio servers in Zelenogorsk, in the military area near M B Zeleno. I was inside one of the barracks buildings and closed all of the doors behind me. My food and water levels were full, blood and health were in the yellow but recovering. In other words, I was in no position to die. As I opened one of the doors, I suddenly dropped dead. I was streaming, so I went back and watched the VOD, frame-by-frame. There was no one on the other side of the door, nor behind me as I had closed the doors and none had opened. I didn't hear any gunshots either. There is no reason I should have died. Again, I was not dying, and no one was around.
What could have caused this? Was there a mod that killed me? Or was there some sort of hacker nearby? Either way, this should not be happening, as I was very kitted out and now have to start over.
