REDSAC: Glitched under map when driving out of vehicle supply station with tank.

I grabbed a tank for the first time, and when I drove out of the vehicle supply station at Chemical Storage, I glitched underneath the map. The tank disappeared, and I couldn’t switch or fire weapons. However, I was still able to ping enemies and locations. My friends could only see me on the map, and my character appeared to be swimming in water while moving down there.

Unfortunately, I wasn’t able to record the moment the glitch happened, only right after. But here’s a short clip of me trying to figure out what’s going on. :)
