The current map in LWOrange (Trinity? Three oceans and a three-pronged mountain range with a TT in the middle of a circle of mountains) has a broken strat zone on the northern front line of the western country. Only two of the factories work; the rest stay at 0% forever.
A Wirblewind's turret will continue to "fire" after it's dead. The Wirblewind himself cannot see it, but all the players around him will see his tracers flying through the air when he pulls the trigger.
If you disable tracers on your end, you cannot see your own tracers in a Wirblewind or Ostwind, but everyone else can.
Either the P-51B's red overall-fuel marker is not calibrated correctly or 50% fuel is not literally half of full capacity. Was using the default skin.
