I can't get blaze rods!

In 0.17.0.2 (or 1.0 beta) there is a bug when I can't get blaze rods! I have killed over ten blazes but they never gave me any! Is this a bug or is it just harder to get blaze rods? I'm not entirely sure, but if it is a bug, can you please fix it quickly? Without blaze rods, I can't get a brewing stand! Oh no!
