Howdy,
Not sure how long this has happened, as I don't GV a whole lot and disco even less, but I disco'd last night in a Sherman and when I came back I had 0 ammo... I was still in the spawn and had not moved out of it.
I don't know if the drop a drop tank and overheat the engine has been fixed in the air, but that was something I experience with the pony for some time. Both kind of hose you depending on what is going on.
