Creepers detonate while far out of range of hurting you. This one is annoying me very much, because my world needs to be perfect(I'm an detailist, and random holes in the ground ruin my world). If a creeper comes up to you, trys to detonate but you're able to move away like 3 blocks from him already, he will still detonate, leaving you unharmed while it just screws up the terrain. Creepers should be frustrating(as in blowing you up with al you're mining stuff) instead off annoying(making you have to fill up the random holes in you're lawn).
