The bug was never fixed. Unless the "fix" was the current state the Crucible drops are in which is not a fix but more .004% bs.
I agree that a fix was never implemented. I didn't set foot into the Crucible until August 2015, and in that month of limited Crucible playtime I got so many weapon drops. I had more Party Crashers or Spare Changes alone drop in that 1 month than I've had all weapons in TTK post game rewards (5 total in TTK, 2 PC+1, 1 Ash Factory, 1 Revelator, and 1 Split Shifter Pro). I've yet to receive an IB weapon as a post game reward, I've bought them all from Saladin.
