Since update 1.5 (Second release of update aquatic) loading existing worlds hangs and fails 80% of the time, when selecting world it will say "updating packs" (or something like that) and will eventually return to the world selection screen, at that point it will not attempt to load any world and app must be restarted

What happens - When selecting a map to load, it moves to loading screen with progress bar and says "updating packs", once this bar has completed it returns to world selection screen. If you then try and select that world or any other to load to selection clicks down and turns green but no world loading takes place.

How can this be recreated - This happens in 80% of cases on this particular tablet, this also happens with a brand new world -not just existing worlds

*NEW* Workaround - By putting the tablet in Airplane mode so the app cannot try to update packs on world load. You need to put the iad into airplane mode, close minecraft and re-open, You can then access worlds
