What happens to all our "loot?" I mean I suppose all of those treasures locked away in chests, just remain locked away until the player comes back. But what if I don't come back? What of those 5 blocks (not ingots) of gold, the 24 diamonds, the piles and piles of redstone, etc.? What of all the home points set? Do they disappear at some point?

I'm more than happy to give it away or drop it somewhere.
