key frag drop bug ?

my key drop reset 2 days ago. i got enough to make one key within in a few games. i usually get enough to make 2 keys pretty quickly. since the reset 5 key frags have dropped. since the last one to drop I've played probably 50 games....mostly wins and nothing is dropping anymore. i usually get enough to make 2 keys within the first day of the reset then I'll get the other 6 frags within the next week or 2. something isn't right , to play that many games and still not get a key frag to make my 2nd key right after the drop reset.
