Background info:
So I was playing with a give command to give me a book that had attribute modifiers. I wanted it to make me move slower, and knowing the operation 0=multiply and operation 1= add, I decided (I have no idea as to how) that to subtract from my speed I would use operation 3.
This isn't an operation.
The command worked.

==================================================================

My problem:
I have a book in my inventory that causes a complete game crash on world startup.

==================================================================

Here's the error:
java.lang.IllegalArgumentException: Invalid operation

==================================================================

What I have tried:
1) Using nbt editors to delete the book from my inventory. I do everything right, but the book comes back after trying to lad the world.
2) Deleting my player.dat file, same issue as 1
3) Using mcedit to delete my player entity, same issue as 1.

==================================================================

Please help me.

Can anyone tell me how to fix this, I have had the world since 1.2, ad it has pretty much everything I've ever built.

Maybe use NBTExplorer to look in u Level.dat.
The Player and his inventory are there to.

Thank you so much.
