You want to know something really stupid?
Anytime I do the deathmatch with fighter jets, at the start of the round when I'm on the ground, my jet simply doesn't move. The engine's on and everything looks otherwise normal, except it's glued in place. Only when I manually respawn, does it properly get moving.
The same glitch persists in the "Formation Flight" flight school lesson that I sometimes do when a daily objective requires it. First attempt, the Besra never leaves the ground, but on second attempt it behaves properly again.
