Description of the issue:

When a lighting rod multiblock is made, and someone uses iron bars instead of steel fence for the extended rod, when it actually gets hit, it causes a game-breaking crash and makes the area unable to be entered again. Affects both servers and SP. Unsure if related, but more than likely not, the thunderstorm was forced using Weather 2's weather machine to make it stormy.
