I got this error when testing out the DSR recipes for stacked mining, In this case, stone but it refuses to mine coal when I unlocked the tech for marking the ores for stacked mining. Also before switching to the DSR recipe I was able to get it to work with Iron, Copper, and Stone but not with Coal even by switching back to normal, Picking it up and back down, etc.

The mod Mining Drones (0.3.24) caused a non-recoverable error.
Please report this error to the mod author.
