So, I decided to randomly dig down in a straight line and I find a cave, finding some Iron along the way. So, I find a creeper and I kill him, revealing gold. I decide to mine it in case I forget with my Iron pick and I get raped from behind by another creeper. When I tried to go back, I just fell to my death, so I decided to place some ladders to ease my fall. It took ages, so when I land, all my stuff is gone. I thought when you died, all the stuff in your inventory flew around the ground.
Fun fact: While typing this, an ad for Star Trek marathon came on. The opening scene was the imfamous "KHAN!"
