I have just finished creating an AFK creeper-skeleton music disc farm. However, in this new update, there is a bug that music disks do not drop after creeper is killed by a skeleton. I spent so much time building this farm, so I would like to have this problem fixed. I have attached the images of this problem in this message as well. The first image is the drops of the farm before several creepers are killed by skeleton, the second one is after several creepers are killed. We can notice that the number of gunpowder increases, but the number of music disc does not increase.
