Top gunner weapon model is stuck

I had the same issue on Xbox One X when I entered a car with a MG on top.

The bug is already listed in the known issues thread

• Spawning into Top Turret (Tanks)
• When squad spawning into a tank, ending up in the top turret position, sometimes you'll end up with an incorrect representation of your weapon and arms (they don't follow your aim). Shooting still works fine, but visually it looks off.
• Status: Fix coming in an upcoming update.
