Redstone Simulator Rewrite

Thanks!

Found two:

// Check to see if PoweredBlocks have invalid items (source is air)
	for (PoweredBlocksList::iterator itr = m_PoweredBlocks.begin(); itr != m_PoweredBlocks.end(); )
	{
		sPoweredBlocks & Change = *itr;

		if (m_World.GetBlock(Change.a_SourcePos) == E_BLOCK_AIR)
		{
			itr = m_PoweredBlocks.erase(itr);
		}
		else if (
			((m_World.GetBlock(Change.a_SourcePos) == E_BLOCK_REDSTONE_WIRE) && (m_World.GetBlockMeta(Change.a_SourcePos) == 0)) ||
			(m_World.GetBlock(Change.a_SourcePos) == E_BLOCK_REDSTONE_TORCH_OFF) ||
			(m_World.GetBlock(Change.a_SourcePos) == E_BLOCK_REDSTONE_REPEATER_OFF) ||
			(m_World.GetBlock(Change.a_SourcePos) == E_BLOCK_INACTIVE_COMPARATOR)
			)
		{
			itr = m_PoweredBlocks.erase(itr);
		}
		else
		{
			itr++;
		}
	}

...and a SetBlock to FastSetBlock.
