I need some hearty souls to help me test Edgeless Square for bugs and errors. Maybe make suggestions for alternative scenarios as well.

Edgeless Square can be seen here.

I don't have the first idea where it is but I can tell you there is one extra territory in your map. It is listed as having 2917 territories despite being a 54 by 54 square (2916)

The shape of your map is a "torus".

Should be pretty easy to find it though. Easiest way I can think of if it is part of the square would be to select all the squares and systematically deselect entire rows, watching for when it loses 55 objects.
Do the same thing for columns and you have it narrowed down to a row and a column.
