Faulty NGS grades corrected

On the morning of Thursday 23 October, NGS came up with some amazing grades. This was due to faulty data input from the Montenegro Swiss Teams, for which several scores of +29999 IMPs were apparently achieved.

This was quickly noticed and the NGS database was reset to how it was before processing this event. Nobody's grade will be affected, but for the moment the Montenegro Swiss Teams is not being graded while the data is corrected.
