Broken radar Missiles

Every time I seem to die to a fox 1 radar missile, it's always an f4s. Whether i'm flying cold, chaffing, or notching, the missile never cares and continues to go for me anyway. In this clip you can see the f4 doesn't even have me locked with his radar, but somehow the missile still goes for me despite pre chaffing and already flying low. As you can see from the sensor view, the f4 never even had me locked when he fired the missile, yet it still goes to my exact location. This doesn't happen with any other radar missile, only the f4s spamming sparrows. Premium bias sure is great
