Something is wrong with version 1.0.2 for me. When I updated from 1.0.1 I got crashes when loading game so I completly removed pack and downloaded 1.0.2 but it was downloading only "logs, resourcepacks and saves" folders. Now I went back to 1.0.1 and everything is fine.
1.0.2 has a weird issue... It crashes back to the desktop after world creation, but you can immediately restart, load and play the world just fine. It also doesn't create the "Cheat Chest" if you select that option, and I was unable to create a playable creative world before 1.0.2 went to recommended. I haven't tried since.
