  I consulted with Hayashi-san, who added the tile features to
PolygonMorph.  The thing is that the PolygonMorph's expects that
"vertices count" is a read only property, but the later change that
StarMorph enhancement brought in affected it and changed it to a read
and write property but didn't add necessary code to support it.

  This "sometimes" you wrote is tricky!  Can you tell us how 
would one reproduce the error?
