Gold cells can contain their position within their box (not to be confused with box number). For example gold cell r8c7 contains either 7 (position in row), 8 (position in column) or 4 (position in box). This means that box 9 also has 1, 4 and 6 available as positions.

I have no idea what I'm missing. Box 9 has only 7,8,9 available as positions but 4 gold cells.
