Ok that went.... poorly.
1 black mark was just a fat finger.
The other one was a first for me. I was filling in the last two squares in a row, a 1 and a 2. They went yellow, but they had to be right... unless I had filled in a square earlier incorrectly. I've never had that happen. So I switched them around as they were definitely wrong. But of course that meant the 1 was black marked as I had a one in it's column already.
So somehow I convinced myself a 1 went somewhere it didn't and that lead to a cascade of errors with 1's. I deleted all the 1's except the one I knew was correct and it went smoothly from there.
