I killed a creeper with arrows many many times, but didn't earn the achievement. Don't know why this is happening, I tried everything, since crafting a new bow and arrows, crafted a new crossbow, tried launching arrows up to hit the creeper in the fall, tried even launching arrows with the dispenser, but anything worked to earn the achievement! Please solve this out. Actually, I think there are more achievements that we can't earn anymore, because of the new versions, so please fix it!
