Sometimes, when you activate the multitasker and later reactivate the game, the world become unplayable because all blocks around you transform in a block with a "primary color", and finally when you try save the world the interface that shows "Your game is saving, dont turn off your dispositive" has gone, is invisible or something like that and the display turn blue. Thank you for your work and effort, that effort gonna be recompensated because you guys, you are like Santa when you give us happines. Thank you.
I don't know why but this bug appears in the 1.6.0.5 version but I can't add this to the field of versions.
Ps. Sorry for my bad English .
