Describe the bug
It seems there is a conflict between the mods Fancy Menu and Create. If I make a schematic using Create, then try to place the Schematic the client crashes whether on a server or singleplayer world. The player data is also corrupted, which has to be cleaned up in NBTExplorer. I originally posted this on the Create issue tracker but was told it was both causing the error.

To Reproduce
Steps to reproduce the behavior:

1. Make a schematic using the Schematic And Quill
2. Write that schematic to an Empty Schematic (item) in a Schematic Table
3. Attempt to place the Schematic in the world or make the Schematic the active item in the hotbar.
4. In singleplayer, the world crashes/client and corrupts the world/player data. On a server is crashes the client and also corrupts the player data, but the world is fine.

Expected behavior
Should be able to make and place schematics without crashing or corrupting data.
