Ok, I see it.

30.Nd6 Bxf6 31.Qxf7+ Z0 ( 31...Kh8 32.Ne8 Ra6 33.Bf8 $18 ) 1-0

Z0 is a nullmove.

As I can see so isn't this covered by the standard. Chessbase have their own
implemation of these too. I don't know about scid, you could try to see how it
save a null move in pgn and use a replace tool on the file.

I didn't follow the pgn debat on rgcc but if this wasn't up someone should
suggest some sort of nullmove/anymove for Steven Edwards so he gets it in when
he revise the standard. Hopefully with something that is easy to do a text
replace on CA/CB files to get them compatible.
