 Because it modifies the vacancy numbers:
 {{{
 sage: B = crystals.infinity.RiggedConfigurations(['A',2])
 sage: RC = RiggedConfigurations(['A',2,1], [[1,1]]*4 + [[2,1]]*4)
 sage: x = B.an_element().f_string([2,2,1,1,2,1,2,1])
 sage: ascii_art(x)
 -4[ ][ ][ ][ ]-4  -4[ ][ ][ ][ ]0
 sage: ascii_art(RC(x))
 0[ ][ ][ ][ ]-4  0[ ][ ][ ][ ]0
 sage: ascii_art(x)
 0[ ][ ][ ][ ]-4  0[ ][ ][ ][ ]0
 }}}
