Issue Description:

What happens:

What happens is when I Try to pick up the conduits with a wrench or break them the game will crash on the instant of the conduit being clicked. Happens with bundles and stray conduits and happens multiple times.

2. Take Pickaxe (or any tool to break conduits)
3. Start breaking the Conduit.
4. The game will crash on click.

may be caused by https://bitbucket.org/Requios/effortless-building/issues

Note: coming from net.minecraft.entity.player.EntityPlayer.getDigSpeed(IBlockState), PlayerEvent.BreakSpeed.getPos() is null (here Forge's Javadoc is wrong, btw), so
Effortless Building is calling BlockState.getBlockHardness() with a null pos.

PS: also, net.minecraft.block.Block.handler$getPlayerRelativeBlockHardness$zzb000(Block.java:2760) which causes the deprecated getDigSpeed() to be called is added by a coremod (no idea which one). getDigSpeed() is normally unused and should not be used.
