I can confirm this as well in 0.15.6
Other than near the blaze spawners, there are no blazes and wither skeletons in nether fortresses.

I noticed it mostly happens when i load a world before the game has conmected itself to XboxLive (it takes about 30 seconds when i turn the game on). If i go into a world quickly, it crashes. But if i wait until i am connected, it doesnt crash.

I have this problem on Ipad Mini 3 , my game randomly crashes and sometimes makes tamed horses disappear, even if it has armor or is tied to a fence. Problem works in creative and survival
