Idk how to reproduce it correctly, but it happens and some of my players are exploiting it

It seems that in some way the plugin tried to waterlog something equals to Y 320

[dadodasyra]

I managed to reproduce it just by placing water on Y 319. I've temporarily set a workaround to avoid a crash with this:

	private static function getBlockLayer(World $world, Vector3 $pos): PalettedBlockArray
	{
        $subChunkY = $pos->getY() >> 4;
        if($subChunkY < Chunk::MIN_SUBCHUNK_INDEX || $subChunkY > Chunk::MAX_SUBCHUNK_INDEX) { //This caused a crash with subchunk 20
            return new PalettedBlockArray(0);
        }

        $subChunk = $world->getChunk($pos->getX() >> 4, $pos->getZ() >> 4)?->getSubChunk($subChunkY);

However, i dont understand and I didnt dived into the code to understand it so I'm pretty sure this is not the way it should be fixed
