Monsters reenabled? Neat-o, now we can build traps

Btw, could it be that creepers aren't dangerous at all anymore? I've been playing a little, and every creeper I encountered (and they all "blew up" in my face) just disappeared after touching me without causing any damage at all. I've been testing that with zombies too, those DO inflict damage. Weird, but I don't mind. Those creepers deserve their name, sneaky little bastards.
