### Express DC Hard -- Two solutions?

Wha?

Code: Select all
` *-------------------* |5 4 3 |6 8 2 |7 9 1|  |7 6 9 |3 1 5 |4 8 2|  |2 8 1 |4 9 7 |3 5 6|  |------|------|-----|  |6 9 5 |2 4 . |. 3 7|  |4 2 4 |9 7 . |. 6 5|  |1 7 8 |5 3 6 |2 4 9|  |------|------|-----|  |3 1 2 |8 6 9 |5 7 4|  |9 4 7 |1 5 3 |6 2 8|  |8 5 6 |7 2 4 |9 1 3|  *-------------------*`

I thought this one was pretty easy for a hard sudoku until I got to the end and realized the last four spots can be filled up with [1,8],[8,1] or [8,1],[1,8]

My attention to detail stinks, have I screwed up somewhere?

Oops, two fours in column 2. Yes, that would be a problem. Sigh, let me start over...
