MCPE will stop and force close while entering the world contains Stronghold or Steve gets near the Stronghold.

Example 1 : The seed contains Stronghold at spawn (Seed: village pls).
I enter the seed and generate the world. The generating bar stops or hangs during generation and then the app automatically closes.

Example 2 : World that contains stronghold that far away from spawn.
The world can generate. I go to the Village with Stronghold and when I come near to the Village, it hangs for several seconds and the app automatically closes.

Please help me to solve this problems. Thank you.
