I wish that if someone joined your airplane / tank and left you wouldn't have to deal with negative ammo counts. I'm not sure if it's just me, yet whenever someone joins my plane or tank and departs during the same sortie I have a negative ammo count when I enter into the gunner position. Also, in GVs if someone joins my tank I can't re-gain control of my turret if the gunner leaves during the same sortie.
Could you please fix this problem HTC?
