IndexOutOfBoundsException in Minecraft LevelRenderer when drill and Borehead mine simultaneously

[wipeX2]

Context

I made a giant drill for a tunnel worm. now this drill incorporates borehead bearings aswell as create drills. Now, when only one of those is active, the crash wont occur. But if both are active at the same time, the game will crash. Provided is a video with a setup on how to replicate the crash.
