The issue is that I get a unique key constraint thrown on a non unique column, the column is indexed but is not unique, this error is driving me up the wall. In my debuging I droped that specific index, it then just crashed on another one, and when I drop all indecies it works, but as soon as I recreate one it starts all over, any ideas out there.
