After updating Actually Additions to 1.10.2-r105, my world crashes with the attached crash reports when the Auto-Breaker.

Minecraft: 1.10.2
Forge Mod Loader: 1.10.2-12.18.3.2239
Actually Additions: 1.10.2-r105
Draconic Evolution: 1.10.2-2.0.8.177
JurassiCraft: 2.0.5
Nether Metals: 1.10.2-1.1.3

Auto-Breaking Amber Ore from JurassiCraft (not added by Nether Metals):

AutoBreaking Ender Draconium Ore or Nether Draconium Ore from Draconic Evolutions:

This is an issue with Nether Metals due to the fact that it uses the parameter swingingHand in its code right here, even though a player (especially a fake player) breaking something doesn't necessarily mean that they are swinging their arm while doing it. The mod should instead use EntityPlayer.getHeldItemMainhand().

Thank you. :) I found someone opened a similar bug with Nether Metals, at MinecraftModDevelopmentMods/NetherMetals#20, after I opened this one. I thought it might be Actually Additions as the Auto-Breaker also crashed with non-Nether Metal ores (e.g. Amber Ore from JurassiCraft) while in the Overworld. Breaking the same blocks I listed above by hand (player with Tinker's Construct pickaxe) worked without issue.
