When I attempt to load into a world, there are three results I've run into: 1) I join on Ruuubick and everything works perfectly fine, 2) I join on literally anyone else and I instead to go an empty instance of that world, even if they're in Beta as well, or 3) It attempts to load the world, fails and sends me back to the loading screen, which after pressing Go puts me at an eternal black screen until I close the game.
