This is a bug I have found earlier today (I don't know if anybody else has found it before). It's not game-breaking, but it's interesting. There is no sound.
Falling into the void within the town will send you to your last "safe location." Since I just respawned after my death, I didn't allow a few seconds for the server to update my safe location - this caused me to go to my previous safe location when I fell into the void: the End. You can't really take advantage of this bug/glitch because it is useless. To get this to work, you must die in the End, respawn in the town, and then fall into the void within about five seconds... failing to fall into the void within five seconds will cause your last safe location to update. Your last safe location will not update if you are in the air.
