What I have thought of
I have prepared some command block as shown in the pictures, to teleport the player to the place where the bobber of the fishing rod is (like a grappling hook)

What happens:
Well, every time I run the "machine", it turns me around, so that I look in a complete different direction than before

Steps to Reproduce:
1. Prepare two command blocks that replaces the same block (one places stone, the other one a redstone block). They must be both triggered by the block they are going to replace (that creates a fast clock):

/setblock ~1 ~ ~ minecraft:stone 0 destroy
/setblock ~ ~ ~1 minecraft:redstone_block 0 destroy

2. Set another command block, which tests for the Entity "unknown" (the bobber of the fishing rod), when it is in the ground
here is the command:

/testfor @e[name=unknown]

3.Set another command block which teleports the player to the bobber:
/tp @p @e[name=unknown]

4. Use the fishing rod in any gamemode and trow out the bobber.

If it helps, I got this "grappling hook" from this video:

Update note: in 14w31a, it doesn't work anymore, i wasn't even tped, the error message says: The entity UUID provided is in an invalid format
I do not know what it could be tough...
