Modpack Version

0.3.1

What happened?

Hit other mobs just fine, but I saved the piglich on a Hostile Mob Network thing and tried to start training its model, and upon hitting one a single time, the server immediately crashes with the log shown. No idea where to start trying to figure out problem.

EDIT: Had my friend try the same thing and we get same effect. Not tied to player or weapon it seems. Trying to use the Hostile Mob Network mod on the Piglich seems to be the main bug.

EDIT 2: Seems its just the piglich. Hostile mob networks doesn't seem to be related at all.

Fixed in the 0.3.2 version, they downgraded DeeperDarker mod and that was the problem.
