STEAM Whiffing to Success Achievement Bugged

AsunaEclipse

Platform: STEAM

I have made this bug report by the due fact that this achievement is bugged im currently achievement hunting and no matter what i do or how many times the killer misses me with an attack and i vault straight after its just stuck on 38/50 and has been for no idea how long im getting no progress on it whatsoever and i know im doing it right too.. as an example i was just in a match with the pig she missed 3 hits on me and i vaulted straight away each time and its still didnt progress from the 38/50.. please fix it as it really shouldnt be bugged..
