Crash at nighttime when Player is in a place with many buildings, light and redstone lamps

In a world of 108 MB when the sun goes down and Player is in a place with many handmade buildings, many torches and some redstone lamps, the app crashes. So you have to either go to bed or leave the place. So annoying! Same bug also appears on the same world on an iPhone 4S. The new update, 0.14.1 didn't fix it.
