The worlds I had before the update won't load-but only the old type worlds.  Infinite worlds work just fine.  I was able to load an old type world once, as soon as the update came out, but after a few minutes the game crashed.  Now whenever I load an old type world it stays on this screen (see attached screenshot). The quote will keep changing, meaning it's not frozen, but the world itself will never actually finish loading.  I've waited at least twenty minutes at one point, to no avail.  It just stays on that screen, never opening the world.  My infinite worlds and old worlds I've created since the updare will load just fine.
