I'm going to try to explain this as clear as possible.

So I was heading back home from a mining trip and was confronted by a group of mobs. Zombies, creepers, spiders and stuff. I killed a few of them and headed into my home. While I was sitting around smelting my stuff in my furnace I heard a grass footstep noise. I knew it was outside because my floor is made of stone brick.

I looked outside my window to see nothing, however the noise kept going on. A few seconds later I heard a creeper starting to hiss and blow up. No sight of the creeper and it blew up a part of my house. The side of the house that got blown up had glass so I could see but there was no creeper there. Plus there is literally no holes in my house.

I'm might not play on that world until it is fixed. By the way I'm using my iOS iPad but it's not in the device list so I put phone.
