@Jack It's already working again in version 1.16.100.59
@ambient I know it was initially for entities. But there are so many posibilities if it gets added to blocks as well. Since it is a block query, I would think it would be supported by blocks. I don't think there's any reason why it should not be added to blocks.
@Jack Valdez 0 is the same as false, so yes if you test if it is equal to 0 it returns true because it is false.
