Whenever i create a survival map and quit to the title, I come back to reopen the save and the world is converted to a creative world. The date is also changed to 12/31/69. everything that i did in the world before i save is still there but my inventory is lost and replaced with a creative inventory.

What I expected to happen was...:
Being able to play on survival, save the game, and open it back up and still be playing survival

What actually happened was...:
Saving the game somehow changes the save to a creative world.

Steps to Reproduce:
1. Start a new survival world
2. play for a few minutes
3. Use the quit to title option
4. return to the minecraft PE menu and select games
5. the save game will still have the same name for the world but is changed to a creative world and also modifys the date near 12/31/69

If it helps at all I am playing on a Samsung Galaxy S 4g with root access, running 4.0.4 ICS
