Put the summary of the bug you're having here

What I expected to happen was the sugar cane would be placed down on a block adjacent to water and the game to run fine.
What actually happened was that the game crashed if I tried to place sugar cane on a block adjacent to water. When I opened it back up, the sugar cane hadn't been placed.

Steps to Reproduce:
1. Open the game in an iPhone 4
2. Open a survival game
3. Break and place sugar cane near water
