(Using Xiaomi Note 4G)
If you fish a boat or minecart, sometimes work, sometimes can't.
The fishing rod sometimes stay there, fly up to sky or fly down to the ground.
If you press the fish button again, it will crash.

UPDATE: If you fish a creeper that is already exploded, it also crashed the game.
