Correctly grabbing blocks with onBlockPlace on a snow tile

It seems that when players place a block on snow it does not return the correct block they have placed for the event. It might be because of how snow is a block and gets replaced when you are placing a block. Does anyone know a good work around to grab the block you are placing in this event?

 

Did you ever figure this out? i just ran into this problem and am about try some tests.

 

Code:

public void onBlockPlace(BlockPlaceEvent event) {

	Block placedBlock = event.getBlock();
	Location blockLocation = placedBlock.getLocation();
	if (event.getBlockReplacedState().getTypeId() == 78)) {
		//block was placed on snow, subtracy one from Y to compensate
		double Ypos = placedBlock.getLocation().getY();
		blockLocation.setY(Ypos - 1);
//load the block at blockLocation, and do whatever you want
	}else{
//normal block placement
	}
}

try that
