Why are you people so disbelieving? I've found plenty of floating islands. That's not even a particularly large one. :tongue.gif:
This is quite true. I encounter floating islands all the time, but typically they're either five blocks entirely (aka too small for even a house), or they're too low to the ground (I found a nice floating plot of land that reminded me of a Vic Viper, oddly enough. I made a door and a hole in it as a cockpit, but it was enclosed in a mountain so it wasn't very scenic, and I soon abandoned it).
