My apologies for the horribly jacked up crash report. Since the updated launcher the game output hasn't worked for me, so I am stuck going through the file explorer and note pad to retrieve it.
Crash occured while I was using a TiC mattock if that matters. I have had the same issue with trying to break sprinkler heads and channels with TiC Mattocks as well. Breaking them by hand has given me no problems, as well as with vanilla tools.

Using 1.10.2 - agricraft-2.0.0-0.8.0-a13.jar
