Ok, added two screenshots. The first shows my wheat farm just before I exit. The second shows it after I restart the world. This is on single player with no other people connected. It doesn't seem to save the growth when I exit.
View of the same wheat farm after I exit and restart. Notice that some of the wheat growth has gone.

I get this too on Android 0.4.0 first revision. I'll get some screenshots.
The other post has been up since the 23rd November and there is still no one assigned.
