Was at the upper biathlon hunting cabins on official chernarus server, no yellow gas (or white when color doesn’t render), and started coughing and bleeding. This has happening a few times where I’ve run into an area and it’s been gas bombed and the gas isn’t visible until I’m inside it coughing and bleeding everywhere. After running out and bandaging, I did a full circle around where the gas would be and couldn’t see it from any angle. Let me know if you need more info. First time bug reporting
