Good evening, Owen!
There is a mistake! I can hear your sob.

But it's not your mistake. I suppose that you have bought the American vinyl board. This board differs from another edition in parts. I described the differences
here and created the "common standard", so everybody could use "his" board but the buyers of the American vinyl board have to be aware that some pathes don't exist on the common standard board. It's truly a pity. Now you can hear me crying.
So your last move (Ds126 - A11 => 4) isn't possible on the standard board. You need 6 moving points to reach A11 on the "standard board". Sorry for this inconvenience.
Greetings
Klaus
