Client Crashed twice on multiplayer server
I was mining the heck out of a cave
Last crash i was mining coal, iron and stone

upgrades on drill were 1+2+3 speed, 3x area, 5x battery
So really fast, maybe too fast :)

Part of the 1.10 all the mods modpack 1.10.2 - 1.6 hotfix

Also had a ring of magnetizing activated.
inventory was full

not sure if the crash reports help

update:
when i relogged i found my battery had just run out. my drill has 437000 charge so possible it ran out before the crash

im able to repeat it. occurs when there are less than 9 blocks being broken.
