Leo 2 unending fires

Greetings people,
Recently been playing German Tanks at top tier and couldn’t help but notice that in case of an engine shot that results in fire breaking out, putting out the fire with the extinguisher does NOT in fact put the fire out, it keeps on burning until reaching the ammo stowage and ultimately killing me in the process. I have been able to put out some fires here and there, but the majority kills me nonetheless. It got a bit disturbing, considering the huge buffs russian tanks have received about their non-combustible ammo as I have seen T tanks fighting while burning and at some point putting out the fire, no explosion no nothing. Is this trully a bug or is it just me being a wehraboo???
