Here’s the Solution grid..

The “notable feature” of the grid, that we were looking for was that it is a Pangram (uses all the letters of the alphabet)

The NINA is the FOUR HUNDRED (highlighted in Green) – since this grid commemorates the completion of 400 games at the FB group 1ACross.

We had also asked for the location of the NINA since we had thrown in a Red herring NINA – highlighted in Red, to “Obtrude” with the effort to get to the Real NINA.
