NetworkHelper API typo

Trying to update AdvancedMachines, keep getting crashes from your NetworkHelper class

specifically using NetworkHelper.announceBlockUpdate(World world, int x, int y, int z)

Looking at code, its fairly obvious why it cannot work in 100% of cases

ic2.common.NetworkHelper line 130:

NetworkManager_announceBlockUpdate.invoke(null, world, x, y, z);

should be

NetworkManager_announceBlockUpdate.invoke(instance, world, x, y, z);

Pls fix kthxbai
