Re: multiple pad sinks in hier block does not work

[Grace Yeung]

    Just in case anyone runs into this.
    
    gr3.10.1 generates hier block code in *.block.yml while gr3.8
    generates code in *.py.block.yml. But GRC was loading the code with
    the old filename extension rather than the new when I was trying to
    modify an existing hier block to generate multiple outputs, hence
    the new changes did not show. And a side note, these files are not
    saved in ~/.grc_gnuradio/ but in the directory where the hier block
    .grc file is generated (I believe this is corrected in a later
    version of gr?).
    
    I also ran into the following error downstream of one of these
    multiple output ports if the Virtual Sink block is used rather than
    say QT GUI Time Sink:
    
    RuntimeError:
          delay(73): insufficient connected output ports (1 needed, 0
          connected)
    
    where the Delay block indicated here is the block right before the
    Virtual Sink.
    
    Is this a bug?
    
    Thanks.
