Issues:
1) Game continues running in "hibernation" mode.
2) After "hibernating" glass panes I put just before disappeared.
3) After some more playing and quitting to title screen, the game didn't properly save, - when I loaded the world back I was in a place some 10-20 minutes before I did the "save", and my inventory was back 40-60 minutes back.

Game version: 0.9.0 Build 3
Android version: Android 4.2.2
Device: Lenovo S6000H

Explanation: Before the last saving bug the game run correctly and saved fine. What I did was go back to the spawn point some 150-300 blocks away for a couple of game days, and when I came back I quit to title. I instantly loaded back in, and I was somewhere half way on my road there, with my inventory from even more time before.
