Issue description:

Original issue: EnigmaticaModpacks/Enigmatica2Expert#248
I broke a rotor with 2 turbine blades on it using OreExcavation (it was the bottom rotor of 7 that used to be part of a mekanism turbine if it matters), and my server crashed.

Steps to reproduce:

1. Place Rotor
2. Attach turbine blades
3. Break Rotor while holding the Ore Excavation key
