Not sure what I was mining this time.

Mod Version: mininggadgets-1.18.1

How strange ! I’ll add a null check here in next version :)

Any idea what block it was that you were mining that caused the crash?

I was clearing out a lush cavern, so the options are kinda limited I guess. At the same time, I finished clearing the area with no further crashes, so I'm not sure.

Maybe one of the following?
Torch
moss carpet
vines
glowberries
short grass

Weird. Let me know if it happens again. Meanwhile I’ll just add a null check ;)
