Infected were attacking vehicle and it seemed when vehicle (Humvee) had taken a few hits it (suspension possibly) had "lifted" and then player gets screen. My friend had been trying to lure the infected away from the building I was in and took the few hits before this happened. He had to relog, but I could still see the vehicle, which looked like the front end was sitting directly on the front wheels while back end looked normal, and even though he relogged, his character was still showing as "driving" the humvee, which he wasn't because he was running around. He could run right through the vehicle because it wasn't loaded on his screen, but I could collide with it as it was still loaded and playing the engine sounds while on my screen.

Unable to interact at all with vehicle after.

I took screenshots so I will attach them to show the after effects.

We also drove a Sarka around earlier in the night and when I took a few turns that caused us to lose control of the vehicle, we went off in the ditch and it did the same thing then almost like when the suspension would be in motion of the vehicle landing on the ground. I didn't get screenshots then.
