Issue description: When you try to break a shield projector with a pickaxe, the game crashes just before it's supposed to break. Tested with Tinkers and Minecraft pickaxes. Removing it with a wrench works.

Steps to reproduce: Place any shield projector, get a pickaxe, break the shield projector

Versions:

• Minecraft: 1.12.2
• Forge: 14.23.2.2618
• McJtyLib: 2.6.4
• RFTools: 7.29

Relevant logs: Crash log

I think I know what happened. Did you try to compose the shield without having a shape card in it or any shield template blocks around it?

The shield projector was just placed, no configurations were changed in it

Will be fixed in the next release. In the meantime, you have a few options to work around it:

• Put a shield template block next to it before breaking it
• Put a shape card in it before breaking it
• Break it in creative mode
• Break it by shift-right-clicking it with a wrench
