131	Unknown invert atom type: N3	Tom Goddard	Eric Pettersen	"Opening mmcif 128d twice gives an error

""Unknown invert atom type: N3""

It doesn't give that error when the first copy is opened, only after the second copy is opened.  Actually sometimes it requires opening 5 or more copies.  The error is not completely reproducible.  I was not able produce the error at all with pdb format 128d.
